Ostara is a pagan holiday named after the Germanic goddess of spring. It's celebrated on March 19-21 depending on the year. You can celebrate by decorating eggs, going on a walk in nature, baking, or making a Faery garden. Some common symbols of Ostara are rabbits/hares, eggs, flowers, and light colors like blue, pink, yellow, and green.
