To calculate an period, you should know the yr of the occasion you are eager about and the system you are utilizing (CE or BCE). After getting that info, you should utilize the next steps:
The right way to Calculate Period
To calculate an period, comply with these steps:
- Know the occasion’s yr.
- Select CE or BCE system.

-
Widespread Period (CE)
