Leap Years: we can do better


Publisher, Matt Parker (Standup Maths), Video, YouTube

2016 is a leap year because it is a multiple of 4 (and not a multiple of 100). The Gregorian Calendar system of leap years gives an average tropical year of 365.2425 days compared to the current true value of 365.2421891, but I think we can do better.
