[It's an interesting enough question, and Derek is just coming back to the apartment from his own jog, so he'll answer while he drinks a cup of coffee and cools down a bit.]

My world has different celebrations for spring depending on the country and who's doing the celebration. The religion I grew up in has a whole month or so where we reflect on our wrongdoings, how to better ourselves for our god, and then at the end, there are religious ceremonies and the like to remember the man who pretty much sacrificed himself to his enemies for everyone elses' sake and their standing with our God, both then and now.

We have a second, kinder in tone celebration for the children; more a celebration of spring than anything, although some say the tradition came from an older religion. They get candy and go hunt for decorated eggs as part of the fun. Not sure what all the symbolism was for originally, though, maybe fertility with the eggs and rabbits.
