Government workers will have a week off for Eid Al Fitr, following orders from President Sheikh Khalifa.
The holiday, beginning Sunday, June 2, and ending Thursday, June 6, was announced by the UAE Cabinet via Twitter on Monday.
Public sector employees will resume work on Sunday, June 9.
It was previously understood that the Eid holiday would begin on Ramadan 29, or Monday June 3, for private and public sector workers and last until Shawwal 3 - which would fall on either Thursday June 6 or Friday June 7, depending on whether Ramadan lasts 29 or 30 days this year.
The length of the month is determined by the UAE's moon-sighting committee.
This year, the UAE Cabinet unified the number of holidays for public and private sector workers. Previously, the public sector would enjoy more days off than private company employees. The UAE Cabinet decree gave both sectors a total of 14 days off a year.
Despite the standardisation of holidays between the two sectors, it was announced on Sunday that private sector employees will have four days off for Eid Al Fitr.
