Eid Al Adha holidays have been announced for public and private sectors in the UAE.
On Twitter, the Federal Authority for Government Human Resources (FAHR) said the four-day holiday will begin on the 9th of the Islamic month, Dhu al-Hijjah and last until the 12th.

That's likely to be around the second week of August.
Earlier this year, the UAE Cabinet had unified the holiday calendar for the public and private sectors.
