February has an extra day in a leap year - February 29th!

It's known as "Leap Day!"

Why?

A year normally has 365 days, but a leap year has 366. We have leap years to adjust our calendar so that the seasons (spring, summer, fall, winter) occur at the same time.

The actual length of a year (the rotation of earth around the sun) is 365.2422 days. If we didn't have leap years, the seasons would shift about a quarter of a day every year, and after 100 years the seasons would be off by 25 days. The extra leap day adjusts this drift. (//Old Farmer's Almanac//)

Which Years Are Leap Years?

Years that are divisible by 4 are leap years.

The Exception: Century years have to be divisible by 400 to be a leap year.

1500 - 1700 - 1900 - 2100 are not leap years* 1600 - 2000 - 2400 are leap years (Time and Date)

How far can you leap? How far can your classmates leap?

Find a place to leap and measure the distance.

Make an Excel graph showing the results of your class or group of friends!

Measure to the closest inch and convert your inches to yards.

A leap is a short run. You take off from one foot and land on the other. It's very dance-like (ballet). A jump is stationary. You jump up from two feet and land on two feet. ......T. Long, PE Teacher

Practice Alliteration!

Write sentences that contain words that start with the letter “L” and also include a form of the word "leap" (leaping, leaped, leaper, etc.).

Examples:

Leapers love little lakes.

Little lizards leap long lengths.

Large llamas like leaping.

Leaping liars like loopholes.

Lonely leapers love lush lights that leak luminescence.

Draw a picture to illustrate one of your alliterations!

1. The modern definition uses the term Blue Moon to mean the second Full Moon in a single calendar month. Using this definition, February is the only month that never has a Blue Moon because the average interval between Full Moons is about 29.5 days. This interval is always greater than the length of February, even in a leap year.) (Blue Moon Frequency)

2. The older, traditional definition of a Blue Moon (Maine Farmers' Almanac) uses the term to mean the third Full Moon in a season which has four Full Moons. Normally a season has three full moons. Using this definition, February occasionally does have a Blue Moon! (Four full moons)
