Islamic hijri date

It would be great to add the Islamic hijri date option in the date format section in klwp, kwgt & klck.

The main issue i see here is that there are many variants of the hijri date

The hijri/lunar date (moon age) is already there i.e. $ai(mage)$, the variations in the date appear due to visually sighting or not sighting the moon at different locations, which can be adjusted by the user accordingly by adding or subtracting 1 or 2 days as per his need. It is the hijri month number & year which are to be calculated.

Thak you for the response.

Yes, I can use moonage for the date but what about month name and year ?
