Thank you for your good question. Ramadan Mubarak!
In fact, the new moon of the blessed month of Ramadan is an opportunity for Muslim communities to come together and be united over the start and the end of Ramadan. It’s unfortunate to see Muslims divided, even within the same community, on when to observe the fast of Ramadan or celebrate the Eid.
Muslim communities should follow their local religious authorities and imams and observe Ramadan fasting and Eids together. Ramadan is a time unity, not division.
It is not acceptable for Muslims living in the same community/city to fast or end their fast of Ramadan on different days.
Though we have diverse methods (the scientific calculations, global moon sighting, or local moon sighting) of how to determine the start and the end of Ramadan, it is not acceptable under any pretext to start or end the fasting of Ramadan with other countries/communities/cities than the country/community/city in which one lives and fasts.
Moreover, it is agreed upon among Muslim scholars that the decision of the people in authority and charge of Muslims’ religious affairs lifts the differences in disputable matters.
Therefore, when the people in charge of the community religious affairs decide to start fasting on a given day, then members of the community should follow this decision, as it is an obedience in goodness, even if the decision differs with other communities.
May Allah accept your and our good deeds, ameen.
Allah Almighty knows best.
