Islamic months (computed)
Dhu al-Qa'dah – Dhu al-Hijjah 1447 AH

With 31 days, May 2026 has four full weeks plus 3 extra days, so Friday, Saturday and Sunday occur five times; every other weekday occurs four times. It has five full Friday-to-Sunday weekends, which only happens in a 31-day month that starts on a Friday.

May 1 is day 121 of the year, so May 2026 covers day numbers 121 to 151. In the Umm al-Qura Islamic calendar, 1 Dhu al-Hijjah 1447 AH falls on May 18 (computed; where months begin with the sighting of the new crescent, the start can differ by a day).
