With 31 days, January 2027 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.

January 1 is day 1 of the year, so January 2027 covers day numbers 001 to 031. In the Umm al-Qura Islamic calendar, 1 Sha'ban 1448 AH falls on January 9 (computed; where months begin with the sighting of the new crescent, the start can differ by a day).
