Totally can relate!!! My ds, who by the way, tested not to be gifted, has been able to tell us (since hes been around age 5 or so) what random day falls on what month/date in say....I don't know, the year 2013, 2020, etc...??? And the kid gets it right every single time!!! It blows my husband and I away. Ds11 has always had an amazing memory for dates, facts, etc...But oddly enough, not tested gifted??? He's the one I would have bet money on...Hit all the Ruf level 3/4's...Strange. Now that's another story...lol
