When even L1s get a certain aspect of English mixed up, you can bet it’s tricky for English language learners to master. This is the case with writing and saying years. Why do we have more than one word to represent an era? Why don’t they have the same position in a sentence? How do we punctuate and capitalize these abbreviations? Let’s clear things up for our students (and possibly forourselves).
- BC stands for “Before Christ” and represents the years before Christ wasborn.
- AD stands for “Anno Domini,” which is Latin for “the year of our Lord,” and represents the years after Christ wasborn.
- BCE stands for “Before Common Era,” “Before Christian Era,” or “Before Current Era” and represents the time before the last 2015 years (at the time this waswritten).
- CE stands for “Common Era,” “Christian Era,” or “Current Era” and represents years 1–2015 (at the time this waswritten).
BC and BCE represent the same time frame, but with BCE, the religious aspect is removed. The same goes for AD and CE (the religious aspect is removed withCE).
- 300 BC
- AD 2015
- 300 BCE
- 2015 CE
BC, BCE, and CE come after the year. Write or say 300BC or 300 before Christ, 300BCE or 300 before common era, and 2015CE or 2015 common era. However, AD comes before the year, so write or say AD2015 or anno Domini 2015. This is because anno Domini is Latin for the year of our Lord, and we always say the year of our Lord before the year (so the year of our Lord2015).
Is 2015AD ever correct? Many people (myself included) were taught that AD stood for after death (after the death of Christ). Some people do write or say AD after the year, but as this is technically incorrect, it is far better to write or say AD2015.
Is it BC or B.C.? BCE or B.C.E.? Well, it depends on which style guide or dictionary you follow. Merriam‑Webster Dictionary (American English) lists these entries with capital letters and no periods/full stops(e.g.,BC), but notes that they are often punctuated and/or written in small capitals (e.g.,B.C.). Oxford Dictionary (British English) and Oxford Canadian Dictionary (Canadian English) also list these entries with capital letters and no periods/full stops (e.g.,BC) and notes they are often written in small capitals, but they don’t list periods/full stops as commonusage.
A popular American style guide, The Chicago Manual of Style, has these entries in capital letters with no periods/full stops(e.g.,BC). This is consistent with many other types of abbreviations that they list (e.g.,US, UK, WA, etc.). In my role as an editor, I’ve noticed that there is definitely a movement away from unnecessarypunctuation.
Show your students examples of these dates in a lesson and then go over the explanation above. Our Famous Places lesson on Nazca Lines includes BC and AD in the first paragraph of the reading.
