Hi Team,

It was a great plugin and we have been using it in our Projects. Our Problem is with the Islamic Calendar. The below is the Islamic Calendar We are Using and this in general called as Islamic Civil Calendar If I am not wrong and Our JDNConevrtibleCalendar is Islamic Civil Calendar Correct me If I am Wrong and the implementation is shown below.

However we needed the Islamic Umm al-Qura calendar Support as this is the standard Calendar using in most of the Muslim Communities. Ref is shown below image

The problem is with the dates here if you could observe, Civil Calendar is having 30 days in that Month where as the Standard Umm al-Qura calendar is having 29 days. Is there any way to achieve this calendar in our JDNConvertible calendar? Please guide us here. Or is there any feature request or road map is there to support this calendar. Please let us know the Possibility and the workaround to achieve this.

Looking forward to hear from you

Sincerely, Praveen Kumar

Hi,

This calendar gives dates in the rule-based Hijri calendar. The Umm al-Qura calendar is not so easy to implement because its rules changed several times and because for some of the months the beginning may be corrected by the authorities. We've to look into this in more detail.

Any updates regarding this issue or could anyone find a solution or a workaround?

Hi,

Thanks for checking but unfortunately there was no progress. I switched jobs and there are no further resources available to work on this. I guess I could help with some limited guidance or a review if someone made a PR.

Would that be a way to go?
