Meghan Gray: 29 and Leap Years (閏年)

Megan Gray

• One Earth's orbit takes 365 days 5 hours 49 mins 16 seconds
• For every year, 1/4 day - 644 secs is shortened.
• For every 4 years, 1 day is added to cancel the shortage of 1 day (1/4 day per year). This still leaves the excess of 2576 secs (644 secs per year).
• For every 100 years, 86400 secs (1 day) is removed (leap year is canceled) from the accumulated excess of 64400 secs. This leaves shortage of 22000 secs after 100 years.
• For every 400 years, 86400 secs (1 day) is added to cancel the shortage of 88000 secs, which leaves shortage of 1600 secs.
