[RESOLVED] Islamic date???

[Zpixel]

is there any module to convert usual date(Julian date) to islamic date.

i think it must be limited to some lines of code and is not too much complicated. but if there is a ready one written in php, i wish to have a look.

thanks for your help.....

I am not aware of any such thing within PHP itself. Certainly there appear to be some 3rd-party items on the web you could look into: http://www.google.com/search?q=php+islamic+calendar

i could finally find by searching:
