Why are there leap years? This lecture explores the astronomical
origins of the calendar. We will discuss lunar and solar calendars and
their hybrids in history and tradition (for example, the Islamic Lunar
Calendar and the Jewish Luni-Solar Calendar), and the Julian and
Gregorian Calendar reforms. Recorded 2006 Oct 4 in 100 Stillman Hall on
the Columbus campus of The Ohio State University.
