The Savior of the Apple Feast Day(sometimes the Saviour on the Hill)[1] is an Eastern Slavic folk holiday, which is observed on August 19, falling on the Feast of the Transfiguration.
It is the most important of the three Saviour (Spas) days. The others are: honey savior, on August 14 (or August 1, Julian Calendar); and nut savior on August 29 (or August 16, Julian Calendar).
The holiday has a pre-Christian origin and is associated with harvesting of ripe fruits, especially apples. Then it became an Orthodox holiday. There are processions and blessings of harvests. Usually, on that day, people from Russia, Ukraine and Belarus eat apples, apple pies, or other dishes containing apples, even if they are not Orthodox Christians.
