Issuing a statement, the Dublin-based council said it has reached the conclusion, based on astronomical calculations, that the first day of the holy month falls on June 28.
The council said it will be possible to sight the new crescent (which shows the beginning of Ramadan) at 11:11 p.m. Makkah time on June 28.
It called on Muslims in Europe and elsewhere in the world to use the opportunity of the holy month to promote Islamic teachings and strengthen Islamic fraternity.
Muslims all around the world fast in Ramadan, that is, abstain from eating and drinking from dawn to sunset.
Ramadan ends with the great feast of Eide Fetr which falls on the first day of the following month, Shavval; Muslims mark the Eid Al-Fetr to celebrate and thank God for having forgiven all their sins in the month of Ramadan.
