11 Hours and Length of Days
Hours and Length of Days The Jews divided the day, from sunrise to sunset, into twelve hours. The length of the hours varied with the length of the day; and the length of the day varied thus (approximately): -
Sun rises. | Sun sets. | |
21st of Adar | 6 o’clock | 6 o’clock = 12 hours. |
21st of Sivan | 5 o’clock | 7 o’clock = 14 hours. |
21st of Elul | 6 o’clock | 6 o’clock = 12 hours. |
21st of Chisleu | 7 o’clock | 5 o’clock = 10 hours. |
Twilight - before sunrise, and after sunset - would vary from three hours (an hour and a half both morning and evening) on the shortest day, to four hours on the longest day (two hours both morning and evening).
