i know this question has probably been answered long ago, but the solar year is 365.24(22?) days long. every 4 years, we have .96 (and some change) left over, therefore we have leap year. but .96 is not 1.00, so shouldnt we "skip" leap year every 25 years? or perhaps, over 100 years, have leap year every 4 years, 5, 5, 5, 4....(adsbygoogle = window.adsbygoogle || []).push({});

the most accurate pattern would be

one leap day every 4 years; one leap day every 5 years; 5; 5; 4; 5; 5; 5; 4; 5; 5; 5; 4; 5; 5; 5; 4; 5; 5; 5; 5|... 21 days/100 years instead of 25/100yrs.
