Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

There are always 24 hours in a day.
February is always 28 days long.
Any 24-hour period will always begin and end in the same day (or week, or month).

How to add a collapsible section in markdown

First, clone your github wiki to your local machine

Checkout your repository wiki via git.
- You can find the URL at the lower-right of your wiki page (look for the label "Clone this wiki locally")
Now that you have pulled down a local copy of your github repo wiki, create a new file in the repo called _Sidebar.md - Note that other names might not work.
Within the newly created _Sidebar.md file, you can add appropriate [[link]] markdown syntax.
Add your new file to the local repository, and push via git push origin master.

With the same procedure, you can add a header(_Header.md) and footer(_Footer.md) file.
