How old is my account? Help me figure it out and you might win a "thanks"!

I'm just curious. I'm trying to find more or less when I started playing but I since deleted the email. It was near the end of the beta if I recall correctly. I checked the page I linked and my "Summoner ID" is in the 96000s. Can you guys help me out by telling me an approximation of your SummonerID and the date it was created? Don't be too specific with your SummonerID though, you might not want to take chances on leaking some information about your account. (No, I can't ask support as they don't reveal that information anymore)
