The Julian Calendar

The Julian Calendar was introduced by Julius Caesar (below) in 46 BC. 

What is the Julian calendar?

It was created for the purpose of not having to add or subtract days in order to keep up with the seasons, which yes they did do before the Julian Calendar.

When Used

This calendar was used from 46 BC to 1582. The calendar after that was The Gregorian Calendar, and before it the Roman Calendar.

How it Works

As said earlier, this calendar is based on the rotation of the earth around the sun. It is still used for predicting certain holidays, ex. certain movable feasts.

Why not often used today

The reason it is not widely used today is because of the mistakes in it. Also, we now more accurate calendars that(in my opinion) are more convenient. Also because this new calendar had one mistake.Every 128 years, one of the tropical days shifted backwards. This made it harder to predict certain days, ex. Easter.

What still used for

Well, for one thing, almost all Orthodox Christian churches celebrate Christmas and Easter according to the Julian Calendar. It is also still followed by many, including the Berber people of North Africa.
