Eidul-Fitr is an important religious holiday celebrated by Muslims worldwide to mark the end of Ramadan, the Islamic holy month of fasting (sawm).
Bangladesh's National Moon-Sighting Committee will meet on Friday to decide whether the country will celebrate Eid on Saturday or Sunday. The date of Eid varies depending on the moon sighting and astronomical calculations.
Abu Dhabi will also be marking the first day of Eid Al Fitr with a fireworks display from 9pm on Friday at Abu Dhabi Corniche and Hazza bin Zayed stadium in Al Ain.
Jama Masjid Shahi Imam made the announcement tonight after a meeting of the moon-sighting committee, a senior official at the city's historic mosque said.
The holy month of Ramadan or Ramzan, observed by the Muslims across the world, is coming to an end.
In 2018, Eid al-Fitr will take place on Friday, June 15 after the crescent moon is seen on the evening of June 14 in Saudi Arabia.
Sharia courts all over the country have also been called on to look out for the crescent moon and inform the committee of any sightings.
During Ramadan, Muslims must abstain from eating, drinking, smoking and sexual activity from dawn to sunset.
The Roads and Transport Authority (RTA) has also confirmed parking timings during the Eid holiday.
"We live in a very fast-paced world and Eid is always special as it gives you a chance to reconnect with your family and friends", the 29-year-old told AFP.
Muslims believe that they are commanded by Allah and are suppose to fast till the last day of Ramadan and pay Zakat-al-Fitr before offering prayers on the occasion of Eid.
