What are AD and BC Systems?
The concepts of AD and BC are correlated which makes them more confusing:
- We use BC (Before Christ) and AD to mark years on calendars.
- This system starts from the year Jesus was believed to be born (though historians aren’t sure of the exact date).
- AD counts years forward from that point, and BC counts backward.
- There’s no year zero, so 1 BC jumps right to 1 AD.
- This system was invented in 525 but didn’t become popular until around 800.
