How do I found out...

Hey guys apologies if this is in the wrong section but how do I find out how old my account is? My friend shouldve played for a year niw but since his register date is "2010" and he has forgotten when he started playing, he doesnt know how long he has to wait until he can get the ribbon for doing so. How can he find out how old his character is? Ide lyk to know how old mine is as well if possible
