A Leapling

is born!

The Leap Year Rhyme

By Raenell DawnLeap Year, Leap Year

When will you be?

Every four years

Then you'll see.

You want more?

We do too!

How many more

can you

Leap to?

Turning 13 is a big deal!

You're now a teenager. But this special birthday can not be celebrated on the date that

Leap Day babies were born on because when we turn 13, it's not a Leap Year. So...

The Leap Day Birthday Rhyme

by Raenell Dawn

There is a girl named Raenell,

who didn't like her birthday very well.

When she turned 13,

she thought it quite mean,

It was her birthday but no one could tell!

WHAT DAY OF THE WEEK IS IT?Another way to tell if it's a Leap Year or not is by what day of the week the year starts and ends on. Every year January 1 and December 31 (the first and last day of the year) fall on the same day of the week. Unless it's a Leap Year.

Leap Yearsonly occur in years that show January 1st landing on one day of the week and December 31 on the following day of the week. See the example below.

OUR BIRTHDAY WEEKEND IN THE OFF YEARS

Eleven times in 100 years February 28 lands on Saturday and March 1 lands on Sunday.

We consider that our Birthday Week-end!Here are the eleven years between 1981 and 2081 that provide(d) such a week-end for us.

Think About These

Leap Year Day Babiesborn in 1884 had no birthday during their entire teen-age years. Why?

Because 1900 was not a Leap Year. In 1888 they were 1@4. In 1892 they were2@8. In 1896 they were 3@12.However, since 1900 was not a Leap Year, they had to wait 8 years before they could celebrate again on February 29.

Making that the only time a Leap Day baby turned 4@20 instead of 4@16. And 5@24 instead of 5@20.Because of that, not one single teenage year was celebrated ON their birth date.

Another way to pose the question is:

Leap Year Day Babies celebrate their birthday on their birth date every four years. But those born in 1884 couldn't celebrate on their 4th birthday when they turned 16. Why?Leap Day babies born in 1984 were able to celebrate turning 4@16 in Leap Year 2000 because it is divisible by 400 and therefore a Leap Year.

Leap Year Day Babieswill never have a "Golden Birthday"

A Golden Birthday is when your age matches the number you were born on. Leap Year Day Babies will have to be 116 before they turn 29 on the 29th

International Date Line Dilemma

The Long and Short of it all! We thought this could be used as a learning tool about the International Date Line.

The L O N G of it...

Longest Reported Leap Day:

Jon Hayanga Leap Year Day Baby 1960, had his birthday in Taipei one day then crossed the international date line going east and had his birthday again the next day in Spokane, WA, USA.

...and The SHORT of it...

Shortest Reported Leap Day:

Ed Chatfield Leap Year Day Baby 1940, crossed the date line in a ship (going west) the night of February 28 woke up on March 1.

TRICK QUESTION

James Collins of Texas, USA, born Leap Day 1968 says:

In a non Leap Year, on February 28th, when they ask, "When's your birthday?" you can tell people this:

"It's the day after today but it's not tomorrow. And it's the day before tomorrow but it's not today."

LEAPING MATH ISSUES

A math book from 1758 uses Leap Year in one of the math lessons. NOTE: Leap Year has a capital L and Y.

ARITHMETICK IN whole & broken numbers DIGESTED AFTER a NEW-METHOD AND CHIEFLY ADAPTED TO THE TRADE OF IRELAND BY ELLIAS VOSTER

Leaping Math Issues1)If Tina was born in 1960, but has only had 13 birthdays, on her birth day, how could she be turning 56 next Leap Year 2016?

Answer: Because 1960 was a Leap Year so Tina must have been born on February 29.

Note: See how it is worded? "on her birth day" - we can only celebrate our birthday ON our birth day, in Leap Years. In annual years we celebrate on different days.

2)If Edwardo was born on February 29, 1956 and in 2012 turned 14 Leap Years on his birthday, how many years old is Edwardo?

(Answer: 56. The key is 14 Leap Years vs. how many "years" without the Leap, literally!)

3)If Chinedu was born February 29, 2000, how many birthdays dill he celebrate, on his birthday, in 2016?

(Answer: 4)

4)If Alitza was born February 29, 1976, how many times did she celebrate her birthday ON her birthday, by 2012?

(Answer: 9 because 9x4=36. In 2012 Alitza turned 36.)
