Does the difference in the timing of the Fajr and Maghrib adhan between Bahrain and Dammam this year mean that the people of Bahrain might have their suhoor after Fajr or break their fast before sunset, based on the belief that there is an error in the calendar?

The time for Fajr prayer begins with the appearance of the second dawn, which is the horizontal whiteness across the horizon. This differs from the false dawn, which is an elongated, column-like whiteness. The time for Maghrib prayer begins with sunset. Referring to the Umm Al-Qura calendar, it is clear that the times for Fajr and Maghrib in Bahrain are slightly earlier than their times in Dammam, with minor differences.
