Ramadan is the 9th month of the Islamic calendar, during which Muslims fast during the day, refraining from eating from sunrise to sunset. Ramadan is either 30 days or 29 days depending on the sighting of the moon, as Islamic months are calculated by the appearance of the new moon. This tool will help you know the number of days remaining until the upcoming Ramadan, with a margin of doubt day. If the moon is not sighted on day 29, day 30 completes the month, and if the moon is sighted, the month is 29 days and the next day is the first day of Ramadan.
