Title: Calendar


1
Calendar History
2
What is the calendar?
The calendar is a system of arranging the year
into days, weeks and months.
3
No one knows who invented the first calendar. No
one knows when the first calendar was invented.
Notched bones recording moon phases have been
found in Africa and Europe. They are from 20,500
B. C. WOW, thats old!
4
Chinese calendar
There are over 30 different calendars used in the
world today!
5
So how did we get the calendar we use today?
6
Our calendar started with the ancient Egyptians.
7
The Egyptians based their calendar on the sun
because of their belief in the sun god Ra.
8
What's next?
9
Julius Cesar was a famous Roman Emperor. He
wanted a new calendar for his empire. He picked
the Egyptian calendar and changed it a little bit.
10
Julius Caesar expanded the Roman empire until it
covered parts of Africa, Asia and Europe.
As the empire grew, the calendar went with
it. That is why European countries use this
calendar.
11
The USA was settled by European colonists who
brought the calendar with them.
12
Thats why we use Julius Caesars calendar!
13
Names of the Months
14
Julius Caesar named the months of the year.
January- the Roman god Janus February- the Roman
purification festival Februa March- the Roman
god Mars April- the old Roman calendar month of
Aprilis May- the Roman goddess Maia June- the
Roman goddess Juno
15
July- named after Julius Caesar August- named for
the Roman emperor Augustus September- from the
Latin septem which means seven October- from the
Latin octo or eight November- from the Latin nove
or nine December- from the Latin decem or ten
16
So why does the ninth month mean seven, the tenth
month mean eight, the eleventh month mean nine
and the twelfth month mean ten? Julius Caesars
calendar started with the month of March and
ended with the month of February. Thats really
strange, isnt it?
17
Do we still use the Julius calendar?
18
The Catholic Pope Gregory XIII (the thirteenth)
changed the calendar again in 1582. Why? Julius
Caesar had counted wrong and the leap years
needed to be changed or Easter would be in the
middle of the summer!
19
We can thank Pope Gregory XIII for the calendar
we have today!
