- The month of March did exist prior to the 17th century, but not in all
- calendars. Precession is figured into the calendar. The seasons will
- not precess across the months. I'm no expert on the Chinese calendar,
- but I believe it is based on the Moon, not the Sun, so a comparison with
- a solar calendar isn't entirely appropriate, but I doubt the new year
- differs from January 1 because of precession.
