The event took place in a cave called Hira , located on the mountain Jabal an-Nour , near Mecca .1 As for the exact date of this event, it has been calculated to be on Friday, the 17th of Ramadan at night, i.e. August 6 , 610 C.E. – when Muhammad was 40 lunar years, 6 months and 12 days of age, i.e. 39 Gregorian calendar years, 3 months and 22 days. 6 August 610 ( Julian ) was actually a Thursday. The proleptic Gregorian calendar is two days ahead in the sixth century and three days ahead in the seventh. In his 1998 book Mubarakpuri sets the event as "Late one Monday night, just before sunrise on the twenty-first of Ramadan (August 10, 610 C.E.)" 10 August 610 was a Monday, the phrase "Late one Monday night, just before sunrise" translating as "early one Monday morning". In The Sealed Nectar Mubarakpuri gives preference to the 21st, noting "Then they differ over the day that the Revelation began."
