It looks like it also has a number of handy additions to the Date
object that might be useful outside of mootools:

There some additions to the Date object like this for jQuery by Joern
Zaefferer and Brandon Aaron here:

If someone wants to build something like the mootools calendar they may
want to use my renderCalendar function to do the boring bit of creating
the calendar:
