On November 28, the Orthodox Church honors the memory of the holy martyrs Aviv, Gurias and Samon.
Also today, Orthodox Christians begin the Nativity Fast.
In the folk calendar, November 28 is Guryev Day, Guriy the Frosty, the Tooth Healer, Winter on a Piebald Mare.
According to folk signs, on Guryev Day you can determine what May will be like.
If it rains or snows on this day, May will be cold and stormy.
If there is a strong wind on Guria Morozny, the bad weather will not subside until mid-December.
If there is a lot of snow, there will be a good harvest.
The loud neighing of horses on Guria foretells a warm winter.
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.
