I was thinking many had their own calendars ... like the Mayans...

but some say ...came from the Pope ... then by Julius Caesar ...




In 1582, when Pope Gregory XIII introduced his Gregorian calendar, Europe adhered to the Julian calendar, first implemented by Julius Caesar in 46 B.C. Since the Roman emperor's system miscalculated the length of the solar year by 11 minutes, the calendar had since fallen out of sync with the seasons.

What is the Difference Between BCE/CE and BC/AD, and Who Came Up with These Systems?
http://www.todayifoundout.com/index.php/2015/11/difference-bce-ce-bc-ad-come/
BCE (Before Common Era) and BC (Before Christ) mean the same thing- previous to year 1 CE (Common Era). This is the same as the year AD 1 (Anno Domini); the latter means “in the year of the lord,” often translated as “in the year of our lord.” (It was thought when the AD dating system was created that its year 1 was the year Jesus of Nazareth was born.)
The Anno Domini system, sometimes called the Dionysian Era or Christian Era, began to catch on among the clergy in Italy relatively soon after and, though not terribly popular, did spread somewhat among the clergy in other parts of Europe. Most notably, in the 8th century, the English monk Bede (now known as the Venerable Bede) used the dating system in his wildly popular Ecclesiastical History of the English People (AD 731).
CE and BCE are much more recent inventions. This started in the 17th century, with the advent of the term Vulgar Era; this wasn’t because people considered it to be an age when everyone was coarse or rude, but because “vulgar” more or less meant “ordinary” or “common”, thus reflecting that the era was “of or belonging to the common people” (from the Latin vulgaris).

As for the actual abbreviation, CE (Common Era) has been claimed to have been used as early as 1831, though I couldn’t find specifically in what work it is supposed to have appeared in. Whatever the case, both it and BCE (Before the Common Era) definitely appeared in Rabbi Morris Jacob Raphall’s Post-Biblical History of the Jews in 1856. The use of BCE and CE was particularly popular in the Jewish community where they were keen to avoid using any nomenclature explicitly referring to Christ as “the lord.” Today, BCE and CE instead of BC and AD has become fairly common among other groups for similar reasons.

Another common system based on the Bible, which for whatever reason wasn’t particularly popular among Western Christians helping to give rise to BC/AD, was Anno Mundi (“in the year of the world” / “year after creation”) or Anno Adami (“in the year of Adam”)- essentially dating things from what was thought to be year 1 of the world. Bede himself used this system in The Reckoning of Time written in 725, six years before Ecclesiastical History of the English People.

The Gregorian calendar was introduced as a refinement of the Julian calendar in 1582, and is today in worldwide use as the de facto calendar for secular purposes.

Then there is the calander system starting in July of 1961.
It is divided into three distinct eras, PM, DM & PD.
PM is the duration of time Pre-Marriage of Tom
DM is the duration of time During Marriage of Tom
PD is the duration of time Post Divorce of Tom.
I am currently in the PD era.

Maybe it was once Sun dials went out of fashion, and Walt Disney needed a fresh income source, or it was probably that dastardly Dutch Colonel, who looked after Elvis so well

You're missing a very important plot point time scholars.

Your calendar in America?
What a weird question...
Basically all first colonists to the new world came from Europe. So you took the European calendar with you. Not so difficult.

Now if you'd ask, what calendar did/do the original Americans have? That's interesting. And I wouldn't know. Mayan/Aztec/Inca? A Moon calendar I suppose.

I think nearly everywhere had a moon calendar before the Romans tried to destroy all other cultures and force their own ways on everyone they could.

Literary scholars and Archaeologists are usually responsible for the divisions in artificial human eras.
eg. KYBC = thousand years before christ.
KYBP = thousand years before present.

who invented the 365 day calendar ...some say Egyptians


Certain difficulties arose, however, because of the inherent incompatibility of lunar and solar years. To solve this problem the Egyptians invented a schematized civil year of 365 days divided into three seasons, each of which consisted of four months of 30 days each.



other ancient calendars ... through the ages -> pretty cool ...

Calendars is one of those topics that stretch way back. Back even before writing.

You see, the seasons were important to life itself and whether primitive man lived or not. During the age when man began planting and harvesting his own crops.

If you check historic sites, you'll find all over the world viewing the heavens was important to them. To know when to plant, when to harvest, was part of life itself.

So some of the first calendars were known as ground calendars. Basically a fixed observation point to look at the night sky, and using what was at the horizon as markers to track the stars in the sky. To know when spring, summer, fall, and winter equinoxes had arrived.

Don't know maybe it was

Hi

Well, a quick google search comes up with:
"The legal code of the United States does not specify an official national calendar. Use of the Gregorian calendar in the United States stems from an Act of Parliament of the United Kingdom in 1751, which specified use of the Gregorian calendar in England and its colonies."

So, based on the OP wording...UK parliament?


I do. And everyone near me should tremble in fear as the Ofsola of Fitsor Nyuk Nyuk is almost upon us. Yet don't despair too long, but revel that the Zlarganth soon follows! Buttons!
