What are the dates of Ramadan? Because the cycle of the lunar calendar does not match the solar calendar, the dates of Ramadan shift by approximately 11 days each year. In 2015, Ramadan is expected to begin on Thursday, June 18, in the United States, although the date is only confirmed once the moon is sighted. The ending of Ramadan is marked by the holiday of Eid ul-Fitr, which takes place either 29 or 30 days after the beginning of the month. On Eid ul-Fitr, morning prayers are followed by feasting and celebration among family and friends.
