On October 1, the Orthodox Church honors the memory of the martyrs Irene and Sophia of Egypt and Ariadne of Promise.
In the folk calendar, October 1st is Arina Rosehip, Arina Autumn, Arina Crane Flight, Arina's Day.
According to folk signs, on Arinin's Day you can find out what the winter will be like.
If there are still leaves on the birch trees, the winter will be warm and quiet.
What the weather is like on the first day of October, that's what it will be like on the first day of April.
If cranes start flying south by Arina's Day, there will be frosts in two weeks; if not, frosts can't be expected until November.
If the east wind blows on Arinin's day, dry weather will set in.
