No one says that you have to celebrate Easter on Easter Sunday or any other holiday on a particular day. You could celebrate with your children either before or after the holiday and still enjoy a festive time together.nA post-Easter celebration might be especially beneficial and more affordable. Once Easter Sunday has passed, the holiday-specific items often wind up in the discount bin. You could buy Easter candy, egg-coloring kits, and decorations for significantly less than you could prior to the holiday.
