Calculating Date in JavaScript

Question

I am currently looking to calculate a custom date in JavaScript and my head is beginning to hurt thinking about it. I have a countdown clock that is to start every other Tuesda

Answer 1

There is a JavaScript implementation of RFC 2445 recurrence rules : http://code.google.com/p/google-caja/source/browse/trunk/src/com/google/caja/demos/calendar/rrule-cajita.js which requires some files in the same directory. See the unit test ( http://code.google.com/p/google-caja/source/browse/trunk/tests/com/google/caja/demos/calendar/rrule_test.js ) for examples of how it works.

Try using it to parse RRULE:FREQ=WEEKLY;BYDAY=TU;INTERVAL=2 which means every second (because of the interval) week (because of the frequency) on Tuesday (because of the byday).
