One of the fun parts of having a late March/early April birthday is that there's a small chance that every once in awhile your birthday will fall on Easter Sunday. This has happened twice for me in my now 33 years of life, and I remember both times. This year Everett is turning 3 on Easter Sunday - he might not remember birthday #3 BUT his next shot will be in 2021 when he'll be turning 14 - he'll definitely remember that one!!
(And just in case you're curious - here's how they figure out when Easter will be: the first Sunday after the first ecclesiastical full moon that occurs after March 21st. So, my next Easter birthday celebration is slated for 2013. And no, I have no concept of lunar calendars, but thanks to google, there is a lovely little list that shows all the calculated dates for this and last century!)
