Common Mistakes When Using “common era”

  • Writing it in lowercase (*'common era'*).

  • Misplacing 'CE' (correct: '1066 CE', not 'CE 1066').

FAQ

Frequently Asked Questions

Yes, in terms of the year count. 2024 CE is the same as AD 2024. The difference is purely terminological and connotational, with CE being a secular alternative.

No, it is most commonly abbreviated as 'CE' after the year number (e.g., 79 CE). The full form is used in explanatory or formal prose.

The term has older origins (Latin 'Vulgaris Aerae' from the 17th century), but its widespread adoption as a secular alternative to AD gained major traction in the late 20th century, especially in academia and publishing.

It depends on context. 'BCE' (Before Common Era) is the secular pairing for 'CE', while 'BC' (Before Christ) pairs with 'AD'. Consistent pairing is key: use either CE/BCE or AD/BC, but do not mix them (e.g., 100 BCE and AD 150 is inconsistent).
