- Overlithe
- A Hobbit holiday.Just like the modern Gregorian calendar, the Shire Calendar regulated time by adding an extra day every four years. 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.
