Overlithe
Overlithe was the Shire Calendar equivalent of leap day in the modern Gregorian calendar. Both calendars must add an extra day every four years to accommodate annual deficits between a 365-day calendar and the actual length of a year (which is a little under a quarter of a day longer). In the Shire Calendar this extra day was known as the Overlithe; it occurred between Mid-year's Day and the second of the two normal Lithedays. It was treated as a special holiday by the inhabitants of the Shire.[1]
