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

A leap
is a short run. You
take
off
from one foot and land on the other. It's very dancelike (ballet).
A jump is stationary. You jump up from two feet and land on two feet. ......T.

Is there
a "Blue
Moon"
during this Leap Year (2004)? _____________
(Blue
Moon Calculator)
Research and learn information about
"Blue Moons".
There are 2 contrasting explanations for when a
"Blue Moon" occurs!
("Blue
Moon")
(Sky
& Telescope)
(Maine
Farmers' Almanac: Four
full moons in a season)
(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)
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)
How
many
leap years during the past 100 years have
had a "Blue
Moon"?
(a.) Write down the years that were
leap years since 1900. Make a table to record
your information  use both "Blue Moon" definitions
and compare!
