Another example of other, perhaps overshadowing influences, is Muslim prayer times. For example, at 47.5 degrees north latitude, in Seattle, WA, US: [https://www.salahtimes.com/usa/seattle] * On the June solstice (2019-06-21), the first prayer was at 03:11 PDT (UTC-7; 2 hours before sunrise) and the last prayer was at 23:11 (2 hours after sunset), 20 hours later. * On the prior December solstice (2018-12-21), the first prayer was at 06:20 PST (UTC-8; 1.5 hours before sunrise) and the last prayer was at 17:55 (1.5 hours after sunset), just 11.5 hours later.
Jewish prayers are similarly affected where the morning prayer times start at about one hour before sunrise and the evening prayer times, about a half hour after sunset. Hence, in the winter months, completing the morning prayer and getting to work on time can sometimes be a challenge. So too, in the summer months, the end of the Sabbath can be somewhat late. _____________________________________ Ephraim Silverberg, CSE System Group, Hebrew University, Jerusalem, Israel.
