How to use a non Gregorian calendar

Hello,

How can I define a non gregorian calendar. That means a full year with 12 months but each month with variable days number. It is a lunar calendar. According to years, a the days number in a month can change?

I don’t find any array for months where I can assign days number for each month.

Thank you for your attenton.
Have a nice day.
