On November 1, the Orthodox Church honors the memory of St. John of Rila and the holy martyr Sadok.
This date is popularly known as Ivanov Day, St. Sadok's Day, Farewell to Autumn, and Welcome of Winter.
According to folk signs, on Ivanov's Day you can make a weather forecast for winter and spring.
If the weather is warm on this day, you can expect a mild winter without severe frosts and a warm spring.
If migratory birds fly low, the winter will be snowless.
If the day turns out to be frosty, it will warm up in a week.
If there are many stars in the sky on the night of Zadok, a cold snap is coming.
