Generation

The Gregorian calendar adds a leap day every 4 years to account for Earth's orbit taking about 365.25 days, but this slightly overcorrects. To fine-tune it, we skip leap years in century years (like 1900) unless they're divisible by 400 (like 2000). This three-part rule—leap if divisible by 4, except if divisible by 100, except if divisible by 400—keeps our calendar aligned with the seasons to within about one day every 3,000 years.
