When Were Calendars Invented?

Do you know when were calendars invented?

This wonderful invention was created by the Sumerians in Mesopotamia as calendars at work did not yet exist until the Bronze Age in 3100 BC.

The Sumerian calendar was very different from what we use today, there were no weeks and an extra month was added every four years.

The first calendar divided a year into 12 lunar months, each consisting of 29 or 30 days.

The Sumerians used the sighting of the first full moon to mark a new month.

Who Invented the Modern Calendar?

Do you know who invented the modern calendar?

In 1582, when Pope Gregory XIII introduced his Gregorian calendar and made it a great success.

Why do Calendars Start On Sunday?

Do you know why do calendars start on Sunday?

Sunday is the day of the week between Saturday and Monday.

In most western countries, Sunday is a day of rest and part of the weekend.

In much of the rest of the world it is considered the first day of the week, as with so many things that have been handed down to us since antiquity.

North American calendars at work continue to use Sunday as the first day, while European calendars at work consider Monday to be the first day.
