The present year, 2021, can be transformed into a
Holocene year
by adding the digit “1” before it, making it 12,021 HE. Years BC/BCE are converted by subtracting the BC/BCE year number from 10,001. Beginning of the Meghalayan age, the current and latest of the three stages in the Holocene era.
What are the 5 ages of man?
