Ostara is one of the names for the spring equinox. (Alban Eilir)
This day the night and day have both the same length, from these days the sun will win its territory,the earth gets fertile again.
Which is celebrated on the 21st of March.
Ostara= the germanic goddess of fertility.

The eggs symbolize fertility and rebirth, that's why they are used in Easter feasts.
