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, of course, it's a Leap Year.
Leap Years only 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.
2007 Monday January 1 - Monday December 31 Not a Leap Year 2008 Tuesday January 1 - Wednesday December 31 Leap Year! 2009 Thursday January 1 - Thursday December 31 Not a Leap Year 2010 Friday January 1 - Friday December 31 Not a Leap Year 2011 Saturday January 1 - Saturday December 31 Not a Leap Year 2012 Sunday January 1 - Monday December 31 Leap Year! 2013 Tuesday January 1 - Tuesday December 31 Not a Leap Year
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
However, sense 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 Year Day Babies will 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.
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.

Leaping Math Issues 1) If Raenell was born in 1960, but has only had 11 birthdays on her birth day,
how could she be 48 in the year 2008?
(Answer: Because 1960 was a Leap Year so Raenell 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.)
2) If Peter was born on February 29, 1956 and in 2008 turned 13 Leap Years on his birthday,
how many years old is Peter?
(Answer: 52. The key is 13 Leap Years vs. how many "years" without the Leap, literally!)
3) If Caroline was born February 29, 2000, how many birthdays did she celebrate, on her
birthday, on 2008?
4) If Jim was born February 29, 1976, how many times did he celebrate his birthday ON his
birthday, by 2005?
(Answer: 7. Seven times four is 28. In 2005 Jim was 29.)
