Calendars
The ancient Babylonians used a calendar with alternating 29- and 30-day months. This system required the addition of an extra month three times every eight years, and as a further adjustment the king would periodically order the insertion of an additional extra month into the calendar.

The Babylonian's added an extra month to their years at irregular intervals.
Their calendar, composed of alternate 29-day and 30-day months, kept roughly in step with the lunar year. To balance the calendar with the solar year, the early Babylonians calculated that they needed to add an extra month three times every eight years.

But this system still did not accurately make up for the accumulated differences between the solar year and the lunar year.
Whenever the king felt that the calendar had slipped too far out of step with the seasons, he ordered another extra month.

However, the Babylonian calendar was quite confused until the 300's B.C., when the Babylonians began to use a more reliable system.

(That would sure confuse me! I wonder what names they gave these..extra months..? )
