We know that there's one minute
If we can fit sixty seconds in it
If we could stack minutes and build a tower
There would be sixty in an hour
When twelve hours pass, then we're halfway
To twenty-four hours, which makes a day
And a week is complete in seven days
But the length of a month is harder to say
They can be twentieth to thirty-one days long
One of them contains a day that you were born on
January, March, May, July, August, October, December
All at thirty-one days, all at thirty-one days
April, June, September, and November
All at thirty days, all at thirty days
February has twenty-eight days
But when it's the leap year
It's got twenty-nine days
It's got twenty-nine days
Yeah, check, check, one, two, listen
Uh, yeah, the length of a year is hard to make clear
Cause one in every four years is a leap year
The common years happen three in a row
They have three-hundred-sixty-five days, you know
Then a leap year comes with an intercalary
That's the name of the extra day in February
That's why leap years have three-hundred-sixty-six days
And why February's number of days can change
January, March, May, July, August, October, December
All at thirty-one days, all at thirty-one days
April, June, September, and November
All at thirty days, all at thirty days
February has twenty-eight days
But when it's the leap year
It's got twenty-nine days
It's got twenty-nine days
Ten years is a decade
One-hundred years is a century
And a millennium's one-thousand years of history
January, March, May, July, August, October, December
All at thirty-one days, all at thirty-one days
April, June, September, and November
All at thirty days, all at thirty days
February has twenty-eight days
But when it's the leap year
It's got twenty-nine days
It's got twenty-nine days
Yeah, one-two, one-two
Yeah, now you know, now you know
That's it
