We know that there’s 1 minute
If we can fit 60 seconds in it.
If we could stack minutes and build a tower,
There would be 60 minutes in 1 hour.
When 12 hours pass, then we’re halfway
To 24 hours, which makes a day.
And a week is complete in 7 days,
But the length of a month is harder to say.
They can be 28 to 31 days long;
One of them contains the day that you were born on!
January, March, May, July, August, October, December:
All have 31 days; all have 31 days.
April, June, September, and November:
All have 30 days; all have 30 days.
February has 28 days, but when it’s a leap year,
It’s got 29 days; it’s got 29 days.
The length of a year is hard to make clear,
‘cause one of every four years is a leap year.
The common years happen three in a row
They have 365 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 366 days
And why February’s number of days can change.
January, March, May, July, August, October, December:
All have thirty-one days; all have thirty-one days.
April, June, September, and November:
All have thirty days; all have thirty days.
February has twenty-eight days, but when it’s a leap year,
It’s got twenty-nine days; it’s got twenty-nine days.
10 years is a decade,
100 years is a century,
And a millennium’s 1000 of history!
