Indonesia, Malaysia, Brunei, Tunisia and Turkey have officially announced the start of the Islamic month of Dhul Hijjah and the dates for Eid al-Adha celebrations. According to Indonesia and Malaysia, Dhul Hijjah will begin on May 18, making May 27 the day of Eid al-Adha in both countries. Tunisia and Turkey have also confirmed May 27 as the date for Eid celebrations.

Brunei, however, reported that the moon for Dhul Hijjah was not sighted, meaning May 18 will be the last day of the previous month, Dhu al-Qa'dah. As a result, Dhul Hijjah will begin there on May 19, and Eid al-Adha will be observed on May 28.

The report also noted that several other Gulf countries are expected to announce their moon-sighting results soon, which will determine their own Eid al-Adha dates.
