On November 19, the Orthodox Church remembers Saint Varlaam of Khutyn and Saint Paul, Archbishop of Constantinople.
In the folk calendar, November 19 is Varlamov's Day, Paul the Confessor, Paul the Icebreaker.
According to folk signs, on Varlamov's day you can determine whether the winter will be snowy.
If it snows on this day, the winter will be snowy.
If there are many stars in the sky on the night of Pavel Ledostav, frost will soon strike.
A cold snap is also expected if there is no wind on Varlamov Day.
If the ice on the rivers is smooth, there will be a good harvest.
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.
