Here’s the cool, nerdy part. Our Earth takes about 365.2422 days to orbit the sun. That little “.2422” is the sneaky bit. If we ignored it, our calendar would drift by a quarter-day each year.
After a few centuries, we’d be celebrating summer in December. Can you imagine Christmas with heat waves and swimming pools? That’s why we add an extra day every four years—to reel the calendar back into alignment.
It’s basically a cosmic tune-up. Think of it like your car’s oil change, but for the entire planet. Neat, right?
But Wait—There’s a Catch!
You might think, “Every four years, easy!” But no, our ancestors made it a bit trickier. There are exceptions. Years divisible by 100 (like 1900) are not leap years, unless they’re also divisible by 400.
So 2000 was a leap year (because 2000 ÷ 400 = 5). But 1900 was not. That tiny rule keeps things super precise. It’s like a secret handshake only mathematicians totally love.
That’s why the next Feb 29 after 2028 will be 2032, then 2036, and so on. Just skip the century years unless they’re divisible by 400. Simple, right? Sure, if you say so.
