My family is a mix of atheists, agnostics, Pagans, Jews and non-denominational Christians, so this time of year is a lot of fun!!
I've got my own things I do for the equinox, but as a family, we're all gathering at my parents' house to dye eggs on Saturday night, some of which we will use in the Passover Seder that evening. The rest we'll eat for breakfast on Easter Sunday and then I'll start cooking dinner, which will include ham, funeral potatoes, green beans with almonds and lots of Martinelli's sparkling apple cider. We're not terribly hung up on any individual traditions, but this is one of the few times a year when my entire family is 1. together and 2. getting along.
