When is Mother's Day 2008?

I kept seeing a lot of ads for Mother's day. I thought it was the way that they start advertising for Valentine's Day on December 26th. I thought "Ohhhh there is plenty of time." Just in case, I decided to look up Mother's day. Apparently, it's on May 11th. For some reason I thought Father's Day was first. Thank goodness that my laptop memory is better than my brain's memory.
