How long is a lunar cycle?
Lunar cycles take about 29.5 days, and many historical cultures found that a natural and useful measurement for timekeeping. For example, knowing how many moons were passing was a good guide to keeping track of changing seasons. Unfortunately, a year is about 365.25 days, which is also a natural and useful measurement for timekeeping. For example, seasons change on a pretty solid annual cycle. And so people who made calendars had to reconcile two not-very-compatible standards of measurement. Ultimately, years won, since keeping track of a stable cycle of years is more useful than a stable cycle of months. However, months remained a useful device for timekeeping. Consequently, calendars tend to contain periods which are at least close to the length of a lunar cycle, even if they don’t quite match.
