Sure, here’s one example for each case:
1 day off: 3650 days before 1907-01-01 is 1897-01-02
2 days off: 3650 days before 2027-01-01 is 2017-01-03
3 days off: 3650 days before 2025-01-01 is 2015-01-04

look I’m not trying to be a dick or anything, but do you not know about leap years and which years they are?
Yes, and I have no idea…
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.
