April 14 – Norse Festival of Sommarsblot. The sommarsblót is a salutation of the rising of the sun over the darkness, in a ceremony that marks the beginning of the second half of the year.

The festival to welcome Summer. The Norse calendar was divided simply in two seasons: summer and winter. At the time around the Christian Easter, which similarly is celebrated according to the lunar calendar, this holiday is also called the Summer Finding, and may be celebrated as early as March 23. It is the day the light of the sun overpowers the darkness. – http://secondsightresearch.tripod.com/bodyandsoul/id19.html
