On October 19, the Orthodox Church honors the memory of Saint Thomas, one of the twelve apostles of Jesus Christ.
In the folk calendar, October 19 is Thomas the Baker, Doubting Thomas, Thomas's Day.
According to folk signs on St. Thomas's Day, one can determine whether to expect bad weather and whether winter will come early.
If the sky is yellow in the morning, bad weather is expected.
Bad weather should also be expected if crows gather in flocks.
If there is no wind on Thomas Khlebnik, cold weather is just around the corner.
If it snows on St. Thomas's Day, winter will come early.
