         The <code>date:add-duration</code> function returns the duration resulting from adding two durations together.
      </p><p>
         Both arguments are strings in the format defined for <code>xs:duration</code> in [<a href="http://www.w3.org/TR/xmlschema-2/#duration" class="offsite">3.2.6 duration</a>] of [<a href="http://www.w3.org/TR/xmlschema-2/" class="offsite">XML Schema Part 2: Datatypes</a>].  If either argument is not in this format, the function returns an empty string (<code>''</code>).
      </p><p>
         The return value is a string in the format defined for <code>xs:duration</code> in [<a href="http://www.w3.org/TR/xmlschema-2/#duration" class="offsite">3.2.6 duration</a>] of [<a href="http://www.w3.org/TR/xmlschema-2/" class="offsite">XML Schema Part 2: Datatypes</a>].
      </p><p>
         The durations can usually be added by summing the numbers given for each of the components in the durations.  However, if the durations are differently signed, then this sometimes results in durations that are impossible to express in this syntax (e.g. <code>'P1M'</code> + <code>'-P1D'</code>).  In these cases, the function returns an empty string (<code>''</code>).

      An implementation of this extension 
      function
      in the EXSLT date namespace must conform to the behaviour described in this document.

      <p>
         The <code>date:add-duration</code> function returns the duration resulting from adding two durations together.
      </p>
      <p>
         Both arguments are strings in the format defined for <code>xs:duration</code> in [<a href="http://www.w3.org/TR/xmlschema-2/#duration" class="offsite">3.2.6 duration</a>] of [<a href="http://www.w3.org/TR/xmlschema-2/" class="offsite">XML Schema Part 2: Datatypes</a>].  If either argument is not in this format, the function returns an empty string (<code>''</code>).
      </p>
      <p>
         The return value is a string in the format defined for <code>xs:duration</code> in [<a href="http://www.w3.org/TR/xmlschema-2/#duration" class="offsite">3.2.6 duration</a>] of [<a href="http://www.w3.org/TR/xmlschema-2/" class="offsite">XML Schema Part 2: Datatypes</a>].
      </p>
      <p>
         The durations can usually be added by summing the numbers given for each of the components in the durations.  However, if the durations are differently signed, then this sometimes results in durations that are impossible to express in this syntax (e.g. <code>'P1M'</code> + <code>'-P1D'</code>).  In these cases, the function returns an empty string (<code>''</code>).

         The <code>date:add</code> function returns the date/time resulting from adding a duration to a date/time.
      </p>
      <p>
         The first argument must be right-truncated date/time strings in one of the formats defined in [<a href="http://www.w3.org/TR/xmlschema-2/" class="offsite">XML Schema Part 2: Datatypes</a>].  The permitted formats are as follows:
      </p>
      <ul>
         <li>
            <a href="http://www.w3.org/TR/xmlschema-2/#dateTime" class="offsite"><code>xs:dateTime</code></a> (<code><var>CCYY</var>-<var>MM</var>-<var>DD</var>T<var>hh</var>:<var>mm</var>:<var>ss</var></code>)
         </li>
         <li>
            <a href="http://www.w3.org/TR/xmlschema-2/#date" class="offsite"><code>xs:date</code></a> (<code><var>CCYY</var>-<var>MM</var>-<var>DD</var></code>)

         <li>
            <a href="http://www.w3.org/TR/xmlschema-2/#gYear" class="offsite"><code>xs:gYear</code></a> (<code><var>CCYY</var></code>)
         </li>
      </ul>
      <p>
         The second argument is a string in the format defined for <code>xs:duration</code> in [<a href="http://www.w3.org/TR/xmlschema-2/#duration" class="offsite">3.2.6 duration</a>] of [<a href="http://www.w3.org/TR/xmlschema-2/" class="offsite">XML Schema Part 2: Datatypes</a>].
      </p>
      <p>
         The return value is a right-truncated date/time strings in one of the formats defined in [<a href="http://www.w3.org/TR/xmlschema-2/" class="offsite">XML Schema Part 2: Datatypes</a>] and listed above.  This value is calculated using the algorithm described in [<a href="http://www.w3.org/TR/xmlschema-2/#adding-durations-to-dateTimes" class="offsite">Appendix E Adding durations to dateTimes</a>] of [<a href="http://www.w3.org/TR/xmlschema-2/" class="offsite">XML Schema Part 2: Datatypes</a>].

      </p><p>
         If there is a <code>name</code> attribute, then the element declares a named date format; otherwise, it declares the default date format. The value of the <code>name</code> attribute is a <a href="http://www.w3.org/TR/REC-xml-names#NT-QName" class="offsite">QName</a>, which is expanded as described in [<a href="http://www.w3.org/TR/xslt#qname" class="offsite">2.4 Qualified Names</a>] of [<a href="http://www.w3.org/TR/xslt" class="offsite">XSLT</a>]. It is an error to declare either the default date format or a date format with a given name more than once (even with different import precedence), unless it is declared every time with the same value for all attributes (taking into account any default values).
      </p><p>
         The <code>calendar</code> attribute specifies the calendar used to interpret format strings using the date format.  The value must be a <a href="http://www.w3.org/TR/REC-xml-names#NT-QName" class="offsite">QName</a>. If the <a href="http://www.w3.org/TR/REC-xml-names#NT-QName" class="offsite">QName</a> does not have a prefix, then it identifies calendar specified in this document and must be <code>gregorian</code>. If the <a href="http://www.w3.org/TR/REC-xml-names#NT-QName" class="offsite">QName</a> has a prefix, then the <a href="http://www.w3.org/TR/REC-xml-names#NT-QName" class="offsite">QName</a> is expanded into an expanded-name as described in [<a href="http://www.w3.org/TR/xslt#qname" class="offsite">2.4 Qualified Names</a>] of [<a href="http://www.w3.org/TR/xslt" class="offsite">XSLT</a>]; the expanded-name identifies the calendar; the interpretation of the format pattern used in the <a href="/date/functions/format-date"><code>date:format-date</code></a> and <a href="/date/functions/parse-date"><code>date:parse-date</code></a> functions in this case is not specified by this document.  If the processor does not support the calendar used by the date format used in these functions, the result of these functions is an empty string (<code>''</code>).
      </p><p>
         If there is no <code>calendar</code> attribute or it has the value <code>gregorian</code>, then the date/time being processed is interpreted as using the Gregorian calendar, with the same assumptions as made by the JDK 1.1 <a href="http://java.sun.com/products/jdk/1.1/docs/api/java.util.GregorianCalendar.html" class="offsite">GregorianCalendar</a> class.  If this date format is used by the <a href="/date/functions/format-date"><code>date:format-date</code></a> or <a href="/date/functions/parse-date"><code>date:parse-date</code></a> function, then the format pattern strings that they use must be in the syntax specified by the JDK 1.1 <a href="http://java.sun.com/products/jdk/1.1/docs/api/java.text.SimpleDateFormat.html" class="offsite">SimpleDateFormat</a> class.  The format pattern string is interpreted as described for the JDK 1.1 <a href="http://java.sun.com/products/jdk/1.1/docs/api/java.text.SimpleDateFormat.html" class="offsite">SimpleDateFormat</a> class.
      </p><p>
         The <code>lang</code> attribute specifies the language of the strings used in formatting the date; it has the same range of values as xml:lang [<a href="http://www.w3.org/TR/1998/REC-xml-19980210" class="offsite">XML</a>]; if no <code>lang</code> value is specified or if the processor does not support the specified language, the language should be determined from the system environment.
      </p><p>
         The <code>first-day-in-week</code> attribute specifies the day that's used as the first day of the week for calculating numbers of the week in month, week in year and day in week.  If the calendar is Gregorian, then it must be one of the strings <code>sunday</code>, <code>monday</code>, <code>tuesday</code>, <code>wednesday</code>, <code>thursday</code>, <code>friday</code> or <code>saturday</code>.  Otherwise the values are restricted based on the calendar being used for the date format.

         The date/time string format must include a time zone, either a <code>Z</code> to indicate Coordinated Universal Time or a <code>+</code> or <code>-</code> followed by the difference between the difference from <acronym>UTC</acronym> represented as <code><var>hh</var>:<var>mm</var></code>.

      An implementation of this extension 
      function
      in the EXSLT date namespace must conform to the behaviour described in this document.

         The <code>date:date</code> function returns the date specified in the date/time string given as the argument.  If no argument is given, then the current local date/time, as returned by <code>date:date-time</code> is used as a default argument.
      </p><p>
         The date/time string specified as an argument must be a string in the format defined as the lexical representation of either <code>xs:dateTime</code> in [<a href="http://www.w3.org/TR/xmlschema-2/#dateTime" class="offsite">3.2.7 dateTime</a>] or <code>xs:date</code> in [<a href="http://www.w3.org/TR/xmlschema-2/#date" class="offsite">3.2.9 date</a>] of [<a href="http://www.w3.org/TR/xmlschema-2/" class="offsite">XML Schema Part 2: Datatypes</a>].  If the argument is not in either of these formats, <code>date:date</code> returns an empty string (<code>''</code>).
      </p><p class="note">
         The date/time format is basically <code><var>CCYY</var>-<var>MM</var>-<var>DD</var>T<var>hh</var>:<var>mm</var>:<var>ss</var></code>, although implementers should consult [<a href="http://www.w3.org/TR/xmlschema-2/" class="offsite">XML Schema Part 2: Datatypes</a>] and [<a href="http://www.iso.ch/markete/8601.pdf" class="offsite">ISO 8601</a>] for details.
      </p><p>
         The date is returned as a string with a lexical representation as defined for <code>xs:date</code> in [<a href="http://www.w3.org/TR/xmlschema-2/#date" class="offsite">3.2.9 date</a>] of [<a href="http://www.w3.org/TR/xmlschema-2/" class="offsite">XML Schema Part 2: Datatypes</a>].

      </p><p>
         If no argument is given or the argument date/time specifies a time zone, then the date string format must include a time zone, either a <code>Z</code> to indicate Coordinated Universal Time or a <code>+</code> or <code>-</code> followed by the difference between the difference from <acronym>UTC</acronym> represented as <code><var>hh</var>:<var>mm</var></code>.  If an argument is specified and it does not specify a time zone, then the date string format must not include a time zone.

      function
      in the EXSLT date namespace must conform to the behaviour described in this document.

      <p>
         The <code>date:date</code> function returns the date specified in the date/time string given as the argument.  If no argument is given, then the current local date/time, as returned by <code>date:date-time</code> is used as a default argument.
      </p>
      <p>
         The date/time string specified as an argument must be a string in the format defined as the lexical representation of either <code>xs:dateTime</code> in [<a href="http://www.w3.org/TR/xmlschema-2/#dateTime" class="offsite">3.2.7 dateTime</a>] or <code>xs:date</code> in [<a href="http://www.w3.org/TR/xmlschema-2/#date" class="offsite">3.2.9 date</a>] of [<a href="http://www.w3.org/TR/xmlschema-2/" class="offsite">XML Schema Part 2: Datatypes</a>].  If the argument is not in either of these formats, <code>date:date</code> returns an empty string (<code>''</code>).
      </p>
      <p class="note">
         The date/time format is basically <code><var>CCYY</var>-<var>MM</var>-<var>DD</var>T<var>hh</var>:<var>mm</var>:<var>ss</var></code>, although implementers should consult [<a href="http://www.w3.org/TR/xmlschema-2/" class="offsite">XML Schema Part 2: Datatypes</a>] and [<a href="http://www.iso.ch/markete/8601.pdf" class="offsite">ISO 8601</a>] for details.
      </p>
      <p>
         The date is returned as a string with a lexical representation as defined for <code>xs:date</code> in [<a href="http://www.w3.org/TR/xmlschema-2/#date" class="offsite">3.2.9 date</a>] of [<a href="http://www.w3.org/TR/xmlschema-2/" class="offsite">XML Schema Part 2: Datatypes</a>].
      </p>
      <p class="note">
         The date format is basically <code><var>CCYY</var>-<var>MM</var>-<var>DD</var></code>, although implementers should consult [<a href="http://www.w3.org/TR/xmlschema-2/" class="offsite">XML Schema Part 2: Datatypes</a>] and [<a href="http://www.iso.ch/markete/8601.pdf" class="offsite">ISO 8601</a>] for details.
      </p>
      <p>
         If no argument is given or the argument date/time specifies a time zone, then the date string format must include a time zone, either a <code>Z</code> to indicate Coordinated Universal Time or a <code>+</code> or <code>-</code> followed by the difference between the difference from <acronym>UTC</acronym> represented as <code><var>hh</var>:<var>mm</var></code>.  If an argument is specified and it does not specify a time zone, then the date string format must not include a time zone.

         The <code>date:day-abbreviation</code> function returns the abbreviation of the day of the week of a date.  If no argument is given, then the current local date/time, as returned by <code>date:date-time</code> is used the default argument.
      </p><p>
         The date/time string specified as the argument is a left or right-truncated string in the format defined as the lexical representation of <code>xs:dateTime</code> in one of the formats defined in [<a href="http://www.w3.org/TR/xmlschema-2/" class="offsite">XML Schema Part 2: Datatypes</a>].  The permitted formats are as follows:
      </p><ul><li><a href="http://www.w3.org/TR/xmlschema-2/#dateTime" class="offsite"><code>xs:dateTime</code></a> (<code><var>CCYY</var>-<var>MM</var>-<var>DD</var>T<var>hh</var>:<var>mm</var>:<var>ss</var></code>)
         </li><li><a href="http://www.w3.org/TR/xmlschema-2/#date" class="offsite"><code>xs:date</code></a> (<code><var>CCYY</var>-<var>MM</var>-<var>DD</var></code>)
         </li></ul><p>
         If the date/time string is not in one of these formats, then the empty string (<code>''</code>) is returned.
      </p><p>
         The result is a three-letter English day abbreviation: one of <code>'Sun'</code>, <code>'Mon'</code>, <code>'Tue'</code>, <code>'Wed'</code>, <code>'Thu'</code> or <code>'Fri'</code>.
      </p></div><p>
      An implementation of this extension 
      function
      in the EXSLT date namespace must conform to the behaviour described in this document.

      <p>
         The <code>date:day-abbreviation</code> function returns the abbreviation of the day of the week of a date.  If no argument is given, then the current local date/time, as returned by <code>date:date-time</code> is used the default argument.
      </p>
      <p>
         The date/time string specified as the argument is a left or right-truncated string in the format defined as the lexical representation of <code>xs:dateTime</code> in one of the formats defined in [<a href="http://www.w3.org/TR/xmlschema-2/" class="offsite">XML Schema Part 2: Datatypes</a>].  The permitted formats are as follows:
      </p>
      <ul>
         <li>
            <a href="http://www.w3.org/TR/xmlschema-2/#dateTime" class="offsite"><code>xs:dateTime</code></a> (<code><var>CCYY</var>-<var>MM</var>-<var>DD</var>T<var>hh</var>:<var>mm</var>:<var>ss</var></code>)
         </li>
         <li>
            <a href="http://www.w3.org/TR/xmlschema-2/#date" class="offsite"><code>xs:date</code></a> (<code><var>CCYY</var>-<var>MM</var>-<var>DD</var></code>)
         </li>
      </ul>
      <p>
         If the date/time string is not in one of these formats, then the empty string (<code>''</code>) is returned.
      </p>
      <p>
         The result is a three-letter English day abbreviation: one of <code>'Sun'</code>, <code>'Mon'</code>, <code>'Tue'</code>, <code>'Wed'</code>, <code>'Thu'</code> or <code>'Fri'</code>.

         The <code>date:day-in-month</code> function returns the day of a date as a number.  If no argument is given, then the current local date/time, as returned by <code>date:date-time</code> is used the default argument.
      </p><p>
         The date/time string specified as the argument is a left or right-truncated string in the format defined as the lexical representation of <code>xs:dateTime</code> in one of the formats defined in [<a href="http://www.w3.org/TR/xmlschema-2/" class="offsite">XML Schema Part 2: Datatypes</a>].  The permitted formats are as follows:
      </p><ul><li><a href="http://www.w3.org/TR/xmlschema-2/#dateTime" class="offsite"><code>xs:dateTime</code></a> (<code><var>CCYY</var>-<var>MM</var>-<var>DD</var>T<var>hh</var>:<var>mm</var>:<var>ss</var></code>)
         </li><li><a href="http://www.w3.org/TR/xmlschema-2/#date" class="offsite"><code>xs:date</code></a> (<code><var>CCYY</var>-<var>MM</var>-<var>DD</var></code>)
         </li><li><a href="http://www.w3.org/TR/xmlschema-2/#gMonthDay" class="offsite"><code>xs:gMonthDay</code></a> (<code>--<var>MM</var>-<var>DD</var></code>)
         </li><li><a href="http://www.w3.org/TR/xmlschema-2/#gDay" class="offsite"><code>xs:gDay</code></a> (<code>---<var>DD</var></code>)
         </li></ul><p>
         If the date/time string is not in one of these formats, then <code>NaN</code> is returned.
      </p></div><p>
      An implementation of this extension 
      function
      in the EXSLT date namespace must conform to the behaviour described in this document.

      <p>
         The <code>date:day-in-month</code> function returns the day of a date as a number.  If no argument is given, then the current local date/time, as returned by <code>date:date-time</code> is used the default argument.
      </p>
      <p>
         The date/time string specified as the argument is a left or right-truncated string in the format defined as the lexical representation of <code>xs:dateTime</code> in one of the formats defined in [<a href="http://www.w3.org/TR/xmlschema-2/" class="offsite">XML Schema Part 2: Datatypes</a>].  The permitted formats are as follows:
      </p>
      <ul>
         <li>
            <a href="http://www.w3.org/TR/xmlschema-2/#dateTime" class="offsite"><code>xs:dateTime</code></a> (<code><var>CCYY</var>-<var>MM</var>-<var>DD</var>T<var>hh</var>:<var>mm</var>:<var>ss</var></code>)
         </li>
         <li>
            <a href="http://www.w3.org/TR/xmlschema-2/#date" class="offsite"><code>xs:date</code></a> (<code><var>CCYY</var>-<var>MM</var>-<var>DD</var></code>)
         </li>
         <li>
            <a href="http://www.w3.org/TR/xmlschema-2/#gMonthDay" class="offsite"><code>xs:gMonthDay</code></a> (<code>--<var>MM</var>-<var>DD</var></code>)
         </li>
         <li>
            <a href="http://www.w3.org/TR/xmlschema-2/#gDay" class="offsite"><code>xs:gDay</code></a> (<code>---<var>DD</var></code>)
         </li>
      </ul>
      <p>
         If the date/time string is not in one of these formats, then <code>NaN</code> is returned.

         The <code>date:date-format</code> element declares a <code>date format</code>, which controls the interpretation of a format pattern used by the <a href="/date/functions/format-date"><code>date:format-date</code></a> and <a href="/date/functions/parse-date"><code>date:parse-date</code></a> functions.
      </p><p>
         If there is a <code>name</code> attribute, then the element declares a named date format; otherwise, it declares the default date format. The value of the <code>name</code> attribute is a <a href="http://www.w3.org/TR/REC-xml-names#NT-QName" class="offsite">QName</a>, which is expanded as described in [<a href="http://www.w3.org/TR/xslt#qname" class="offsite">2.4 Qualified Names</a>] of [<a href="http://www.w3.org/TR/xslt" class="offsite">XSLT</a>]. It is an error to declare either the default date format or a date format with a given name more than once (even with different import precedence), unless it is declared every time with the same value for all attributes (taking into account any default values).
      </p><p>
         The <code>calendar</code> attribute specifies the calendar used to interpret format strings using the date format.  The value must be a <a href="http://www.w3.org/TR/REC-xml-names#NT-QName" class="offsite">QName</a>. If the <a href="http://www.w3.org/TR/REC-xml-names#NT-QName" class="offsite">QName</a> does not have a prefix, then it identifies calendar specified in this document and must be <code>gregorian</code>. If the <a href="http://www.w3.org/TR/REC-xml-names#NT-QName" class="offsite">QName</a> has a prefix, then the <a href="http://www.w3.org/TR/REC-xml-names#NT-QName" class="offsite">QName</a> is expanded into an expanded-name as described in [<a href="http://www.w3.org/TR/xslt#qname" class="offsite">2.4 Qualified Names</a>] of [<a href="http://www.w3.org/TR/xslt" class="offsite">XSLT</a>]; the expanded-name identifies the calendar; the interpretation of the format pattern used in the <a href="/date/functions/format-date"><code>date:format-date</code></a> and <a href="/date/functions/parse-date"><code>date:parse-date</code></a> functions in this case is not specified by this document.  If the processor does not support the calendar used by the date format used in these functions, the result of these functions is an empty string (<code>''</code>).
      </p><p>
         If there is no <code>calendar</code> attribute or it has the value <code>gregorian</code>, then the date/time being processed is interpreted as using the Gregorian calendar, with the same assumptions as made by the JDK 1.1 <a href="http://java.sun.com/products/jdk/1.1/docs/api/java.util.GregorianCalendar.html" class="offsite">GregorianCalendar</a> class.  If this date format is used by the <a href="/date/functions/format-date"><code>date:format-date</code></a> or <a href="/date/functions/parse-date"><code>date:parse-date</code></a> function, then the format pattern strings that they use must be in the syntax specified by the JDK 1.1 <a href="http://java.sun.com/products/jdk/1.1/docs/api/java.text.SimpleDateFormat.html" class="offsite">SimpleDateFormat</a> class.  The format pattern string is interpreted as described for the JDK 1.1 <a href="http://java.sun.com/products/jdk/1.1/docs/api/java.text.SimpleDateFormat.html" class="offsite">SimpleDateFormat</a> class.
      </p><p>
         The <code>lang</code> attribute specifies the language of the strings used in formatting the date; it has the same range of values as xml:lang [<a href="http://www.w3.org/TR/1998/REC-xml-19980210" class="offsite">XML</a>]; if no <code>lang</code> value is specified or if the processor does not support the specified language, the language should be determined from the system environment.
      </p><p>
         The <code>first-day-in-week</code> attribute specifies the day that's used as the first day of the week for calculating numbers of the week in month, week in year and day in week.  If the calendar is Gregorian, then it must be one of the strings <code>sunday</code>, <code>monday</code>, <code>tuesday</code>, <code>wednesday</code>, <code>thursday</code>, <code>friday</code> or <code>saturday</code>.  Otherwise the values are restricted based on the calendar being used for the date format.
      </p></div><h2>Implementations</h2><p>There are currently no XSLT processors that we know of that support <code>date:date-format</code> natively.</p><p>There are currently no third-party implementations of <code>date:date-format</code>.</p></td></tr></table><div id="colophon"><p><a href="http://www.exslt.org/date/elements/date-format/index.html">http://www.exslt.org/date/elements/date-format/index.html</a> last modified 2001-05-13</p></div></body></html>

         The <code>date:add-duration</code> function returns the duration resulting from adding two durations together.
      </p><p>
         Both arguments are strings in the format defined for <code>xs:duration</code> in [<a href="http://www.w3.org/TR/xmlschema-2/#duration" class="offsite">3.2.6 duration</a>] of [<a href="http://www.w3.org/TR/xmlschema-2/" class="offsite">XML Schema Part 2: Datatypes</a>].  If either argument is not in this format, the function returns an empty string (<code>''</code>).
      </p><p>
         The return value is a string in the format defined for <code>xs:duration</code> in [<a href="http://www.w3.org/TR/xmlschema-2/#duration" class="offsite">3.2.6 duration</a>] of [<a href="http://www.w3.org/TR/xmlschema-2/" class="offsite">XML Schema Part 2: Datatypes</a>].
      </p><p>
         The durations can usually be added by summing the numbers given for each of the components in the durations.  However, if the durations are differently signed, then this sometimes results in durations that are impossible to express in this syntax (e.g. <code>'P1M'</code> + <code>'-P1D'</code>).  In these cases, the function returns an empty string (<code>''</code>).
