Reply to comment by Subterrainio in Ancient Chinese text reveals earliest known record of auroral display, described as a ‘five-colored light’ event in either 977 or 957 BCE by marketrent

The common era is the dating system we use now, we're in the year 2023 of the Common Era (CE). Before the year 1 CE there was the year 1 BCE (Before Common Era), and we count backwards from there.

It's the exact same system used with BC (Before Christ) and AD (Anno Domini). It's the year AD 2023, and the year 2023 CE.

Julius Caesar died in 44 BCE, and 44 BC.

Make sense now?
