THE CALENDER

WHO INVENTED THE CALENDAR?

• The ancient Egyptians created it
• Counted number of days between appearance of a star
• The stars name is Sirius
• This way they found out there are 365 days in a year

DIFFICULTIES WITH THE CALENDAR

• They now had to divide the year into smaller parts
• Early people used moon cycles to divide the years
• The Egyptians had 12 months each with 30 days
• They also had 5 days added on

THE ROMANS USE THE CALENDAR

• They added one day to the year every for years
• We know this as a leap year
• By the 1500s spring came ten days to early
• Pope Gregory XIII fixed this and created the calendar we use today
