Well, I was born on April 10th, and I don't think that's a holiday that we celebrate here.
Lets see what Wikipedia [http://en.wikipedia.org/wiki/April_10] has to say on the matter.
Hm, apparently it's the 100th day of the year, that's pretty cool.
The Titanic set sail on April 10th in 1912.
The Belfast Agreement was signed on April 10th in 1998.
So yeah, no holidays here best I can tell. The most interesting thing about my birthday is that my Moms birthday is on the 10th as well, and my Dads is on the 9th. Having three birthdays in two days really kind of sucks actually.
