Twice a year people complain about Daylight Saving Time. It could be worse. 3500 years ago, Egyptians, who created the idea of time based on lunar cycles and the number of stars observable at night, had a different system: 24 hours, but 12 of them day and 10 night. I don’t know how they made nighttime dates since sundials didn’t work well after dark. I wonder, today, would the DST hour go on the day’s span or the night’s?
