Time and Time Again: Calendars Now and Then
Alberto Guzman, Professor Emeritus, City College of NY
Lenoir Nature Center, 19 Dudley St, Yonkers
If you think that it’s 2024, and most of you do, thank Pope Gregory XIII. In 1582, he reformed the Julian calendar (thanks, Julius Cesar) so the months would stay in the right season, no December in summer. It’s the most widely used calendar, even if not the only one around. Muslims, Jews, Chinese, the Eastern Orthodox Church all have different calendars. The calendar has had a long and complicated history. Professor Guzman, a mathematician and an astronomer, will talk about how we have come to think of this year as 2024.
Refreshments at 7 PM, talk at 7:30 PM
