On December 2, the Orthodox Church honors the memory of the Old Testament prophet Obadiah.
In the folk calendar, December 2 is Avdeev Day, Avdey the Radetel.
According to folk signs, on Avdeev Day you can find out whether the winter will be cold and long.
Snow and strong wind on this day foretell a cold and long winter.
If there is a lot of snow, there will be a good harvest next year.
If the wind changes direction, the weather is expected to worsen.
If the wood in the stove crackles, frost will strike.
For reference
A sign is a stable connection between two phenomena of objective reality, one of which is understood as a sign, and the second as its interpretation, usually in the form of a forecast for the future; a linguistic (in the form of an aphorism, paremia) representation of this connection.
