2020 as Earth's history

Description

This demonstration is based upon Carl Sagan's "Cosmic Timeline" for the Universe, except we will start with the formation of our planet as Jan 1, 2020 at 12:00am.

Sample calculation: 

The Precambrian Era lasted from 4.56 Ga to 570 Ma (equivalently = 4560 Ma to 570 Ma)

Each calendar day (there are 366 days in 2020) represents 12,459,016 years (equivalently ~12.459 Ma)

We need to represent 3990 million years (from 4560 million -570 million).  This works out to 320.25 of our 366 available days!  The Precambrian would have lasted from Jan 1, 2020 all the way until Nov 15th, 2020!
