In ancient Latvia, Lieldienas ("big days") was the celebration of Vernal Equinox on March 23. The celebration usually lasted three or four days; each day was devoted to a specific deity, though no source gives the names of the respective deity. At least one day is probably dedicated to Māra.
Lieldienas was a celebration of dancing, singing and gaiety. On the first day, the Latvians arose early and rinsed their faces in running water. Symbolically scattering evil, adults scared birds away from the homes and surroundings.
Eggs were associated with Lieldienas. One who steals an egg will be poor. One who eats a hard-boiled egg without salt is a liar. A girl who gives a boy two eggs doesn't like him; three eggs mean there is a chance she likes; four eggs means she doesn't like him but will be with him because he is richer; five eggs means she loves him.
In modern Latvia, Easter is called Lieldienas. Some of the old traditions survive and are performed at Easter.
