Mid-year's Day is the middle day of the year that roughly corresponds with the summer solstice or Midsummer.
In the context of the Shire-reckoning, the middle day is the second of the Lithedays, falling between 1 Lithe and 2 Lithe, and (as the Overlithe) had no weekday name. In the Shire, the Free Fair is held on the White Downs during these Lithedays.
