Today in exist-open, Slav asked:
Hi, anyone have function for calculate all second Tuesdays for year?
(That is, Patch Tuesdays.)
Below are two approaches—one that solves the problem directly (finding only 2nd Tuesdays) and one more generally (finding any combination of week of the month and day of the week, e.g., 5th Sundays).

This article walks through the process of migrating an eXist application from using old-style fields to using the new, Lucene-based facets and fields. For more information, see the eXist documentation's Lucene article.
In the old-style approach to fields, fields were constructed and maintained manually via the ft:index() function. To add or update fields for a document, a <doc> element containing <field> elements was passed to this function, along with the URI of the resource to be indexed.
For example, in one application, fields were constructed with in the hsa/modules/index.xq library module, whose index:index-one-document() function constructed the <field> elements and passed them to the ft:index() function:
