The length of Islamic lunar calendar months, the ninth of which is Ramadan, varies between 29 and 30 days.
In March, Sharjah Centre for Astronomy and Space Sciences said Ramadan would likely fall on May 17 with Eid Al Fitr, marking the end of the month, expected on June 15.
Last year, Ramadan began in Saudi Arabia on May 26. It is observed as the month of fasting (Sawm) to celebrate the first revelation of the Quran to Prophet Muhammad.
The month is a time for spiritual reflection, improvement and increased devotion and worship. The ongoing tragedies in Yemen, Syria, Iraq, Burma, across Africa and most recently the escalation of violence by Israeli occupied forces against the Palestinians in Gaza cast a shadow of sadness and mourning.
"According to astronomical calculations, the crescent for the month of Ramadan this evening (Tuesday) did not meet the criteria agreed upon by member countries of MABIMS (Brunei Darussalam, Indonesia, Malaysia and Singapore)", read the press release.
"We wish the Muslim community, here and overseas, a very blessed Ramadan".
The Deputy Secretary-General of the NSCIA, Prof Salisu Shehu in a statement yesterday quoted the Sultan as felicitating with Muslims on the occasion of this year's Ramadan fasting and prayed that Allah grant the Ummah the opportunity to maximize the benefits and blessings of the Holy Month.
The president added that Ramadan "reminds us of the richness Muslims add to the religious tapestry of American life".
