Why does the Almanac has only 4 digits of year when the earth existed for millions?

Who stole the Earth Years?

The Earth has existed for millions of years, but mankind has not been keeping track of the date for quite that long. Our current dates are based on the Gregorian calendar, introduced in the 1500s.

That's interesting,,,I am sure many civilizations existed before that had someway of counting time.

There have been, and still are, a lot of different calendars. The one we use now accounts for the four digit year.

The Mayan/Aztec calendar can calculate any date going backwards or forwards for millions/billions/infinity years, days. Their calendars are based on the sun, AND the moon, AND the Milky Way Galaxy rotation.
Each of these calendars works like cogs in a giant wheel.
Mayans start their "new calendars" after every 5,000+ years.
As far as I and people that keep track of these "dates" know, the Mayan calendar is the most extensive and accurate calendar ever invented.
The cogs are:
1. The Haab - very close to our 365 day year
2. The Tzolkin - very close to a lunar style calendar
3. The Long Count Calendar - Each such cycle is calculated to be 2,880,000 days (about 7885 solar years)
So, just by turning the big wheel of time (with the 3 cogs in it), they can calculate any date in the universe.
BTW. - Calendars are man made measurements. Just like a ruler is made for measuring distance, calendars are made for measuring time.
Calendars measure time RELATIVE to our system of measurement and reference points. Time itself is infinite.
