    look I’m not trying to be a dick or anything, but do you not know about leap years and which years they are?

        Leap years are each fourth year, except each hundredth year, except each thousandth year.

        1896 leap year
        1900 not leap year
        1904 leap year
        …
        1996 leap year
        2000 leap year
        2004 leap year
        …
        2096 leap year
        2100 not leap year
        2104 leap year

        Then you just arrange the 10 year window in different positions to overlap 1 to 3 leap years to reveal the three outcomes of the bug.

        - / - - - / - - - /
        - - / - - - / - - -
        - - 0 - - - / - - -

        - is a normal year, / is a leap year, 0 is an exceptional non-leap year.

          Small correction, it’s every fourth year except every hundreth year except every 400th year. I’m assuming the misconception comes from the last time it was a 100th also being a 1000th (2000) but the next time a leap year will end in 00 is 2400
