BCE which stands for "Before the Common Era" is a notation that we use in dating human history according to the Gregorian calendar.

BCE refers to the time before Jesus Christ was born and AD which is Latin for "Common Era" refers to the years after the birth of Jesus including this year, 2021 AD.

Knowing BCE and AD is therefore very important as it allows us to be able to date our history.
