Is the MISRI Calendar of Today Correct?


Unread post by hkirefu » Sun May 09, 2021 1:14 pm

I have attached a document that highlights why the MISRI calendar used today has (may?) unwittingly become inaccurate and why Eid al-Fitra is not on May 12th rather May 13th, 2021. Please assist in providing either evidence to support this position or refute it.

Additional Research: I am looking for sources of information related to the following questions to determine if the Islamic new moon was replaced by the astronomical new moon unwittingly in Islamic Calendars and when this may have occurred.

1. When did the astronomical new moon calculation come into existence and when was it first widely published?
2. Links to various Islamic calendars produced by different communities
3. Islamic calendars both prior and closely after the introduction of the astronomical new moon calculation.

Any sources are greatly appreciated.
