The Mr gazzi calendar
The Sumariens created the calendar that we use today.
No. The mayans made the calendar and this calendar is what we use today.
I can't see "this" calendar.
It is the Gregorian calendar which we use today
the Gregorian calendar says my text book
Gregorian
If you mean 365.25 days in a year then it was the Romans who introduced the calendar that we now use today.
The calendar we use today was made by the Romans under Julius Caesar, thus, it is called the Julian calendar.
Julius Cesar
The Mayans, Egyptians, Babylonians, and Chinese all had calendars in the ancient days. The calendar we use to today was first developed by the Romans, under Julius Caesar (the Julian Calendar). That was modified by the Gregorian Calendar (named for Pope Gregory XIII), which we still use today
It refers to the Gregorian calendar year that we use today as opposed to the ancient Julian calendar year
The Gregorian calendar is the calendar we use today. So, yes, it does have 12 months.
