getDOY() from JQuery Datepicker

Question

is it possible to get the DOY in the Datepicker - I need to disable every 3rd day and could use something like date.getDOY() % 3 === 0

what do you mean by display every third day? do you want to disable all the other days — Arun P Johny, Aug 26 '14 at 01:02

http://stackoverflow.com/questions/8619879/javascript-calculate-the-day-of-the-year-1-366 did not help, that determining if leap year 365 or 366 (why the mark down...) — BarclayVision, Aug 26 '14 at 01:19

The following works until it gets to the next year (Jan 2015) and also fails in 3rd week of March in every year?
