Ostara corresponds with the Christian holiday of Easter. It also corresponds with the 1st day of Spring, sometimes it can be as early as March 19th sometimes as late as March 22nd but is usually celebrated on March 20th. This is the 2nd of the solar festivals and is celebrated as the maiden goddess waking up from her long sleep.
Days are starting to get a little bit longer with nights starting to shorten.
The main symbols for Ostara are rabbits due to their fertile nature, eggs for the same reason and typically the eggs are dyed with natural dyes instead of artifical dyes.
