Eid Mubarak on whichever day you celebrate!
Dar us Salaam, PGMA, ISB, and Dar al Taqwa are celebrating Eid on Friday while MCC, Dar al Hijrah, ADAMS Center, and ISWA are celebrating on Saturday, not yet sure about ICM.
Update: ICM states that there were zero credible sightings anywhere in the world so they are also doing Eid on Saturday.
The Friday group are using the opinion of the crescent moon being sighted anywhere in the world to determine the start and end of Ramadan while the Saturday group is solely using ISNA and the Fiqh Council of North America’s calculations.
Last year, I mentioned that I supported ISNA’s 5 year calendar but I’ve changed my opinion and have withdrawn my previous position.
