"And if you do the math…

365.25 × 4 = 365 + 365 + 365 + 366 = 1461…

The math indeed adds up!" 🙌

"With the SOLAR YEAR being [approximately] 365¼ (365.25) days long compared to the CALENDAR YEAR being 365 days long…

Those are why we have #LeapYears and #LeapDays!" ►

"Back to the original question of us having #LeapYears and #LeapDays, though…

It turns out that the length of time for 1 SOLAR YEAR—

That is—

The precise time our planet makes 1 lap around the sun—

Is just under 365¼ (365.25) days!" 😮

"That's 365 days and 6 hours!" ►

"And here's some UNCOMMON knowledge—

As it is currently…

Do you know the EXCEPTIONS to the 'MULTIPLE of 4' number year rule for #LeapYears and #LeapDays are for years that are a MULTIPLE of 100…

But not those that are a MULTIPLE of 400…?" 😮 ►

"Today is THE Leap Day — February 29!" 😀👉

"Today is February 29—

THE #LeapDay!" 🎉

"Even though this seems like — or maybe NOT like — common knowledge…

Do you know why we have #LeapDays and #LeapYears?

And why we have them EVERY 4 YEARS—

Specifically…

On years of which the number is a MULTIPLE of 4?" 🤔 ►
