Thank you for Your question. ^.^ The holiday coincides with the winter solstice. . This is the boundary of winter and spring.
From very ancient times so see off winter and welcome spring.. And let around snow, but according to the Orthodox calendar it means the coming of spring. And lent begins.
The holiday has been preserved in Russia since pagan times. People always associate spring with the beginning of a new life. A pancake is a symbol of the sun.
It's yellow, round and hot. Therefore, in these festive days we bake a lot of different and delicious pancakes. And entertained all around.
