Ireland has a village with a 365-day calendar In the Irish village of Leap, County Cork, the calendar is said to have been invented in 1680 by Father Patrick Dillon. The village's unique calendar features a 365-day year with an extra day added to the end of the regular year, making it the longest year in the world. This calendar was allegedly created to ensure that the village's feast day of St. Fin Barre would always fall on the same day, and has been observed by the villagers ever since.
