Due to my Transformer fixation, I find I can logically determime what year something happened based on what TF toys I received as presents for Easter, my birthday, (August), and Christmas around the time of the other events.
It did get harder after college though, and it didn't help that TF started to suck just before I graduated (Beast Machines' abbreviation is BM for a reason). Stuff from high school that occured once I could drive gets mixed up with college occasionally, and the string of meaningless retail jobs I've had since college instead of a career are easily confused with my summer jobs during college as well.
