The first day of the Hajj pilgrimage to Mecca in 2017 will be on Wednesday, August 30, 2017, as announced by Saudi Arabia’s High Judicial Court.
In the Islamic calendar, Hajj begins every year on the 8th day of the Dhu al-Hijjah lunar month, and traditionally the length of lunar months is only confirmed after moon sighting on the 29th day of the previous lunar month.
Since the moon was not seen on August 21, the first day of the Dhu al-Hijjah lunar month lunar will be August 23, and so Hajj should begin on August 30.
The High Judicial court in Saudi Arabia announces the dates for Hajj, and Eid al-Adha after reviewing moon sighting reports.
