What is CE mean as in 79 CE?

Answer 1

CE is an abbreviation in relation to the mostly accepted calendar of the western world and it means Common Era, Christian Era and/ or Current Era since there are cultures that are not members of the Christian Community and replaced the earlier adopted by the Gregorian calendar AD [Anno Domini in Latin - Lord's Year].

Hence 79 CE means year 79 Common Era.

Some religions and/ or nations maintain a parallel calendar for the facilitation and time keeping of their rituals like the Hebrew calendar or the Islamic one. In addition the BCE abbreviation was introduced for the Before Christian, Common and Current Era, despite the fact that Ancient Greeks were time keeping their calendar in an ascending format based in the Olympiads, commencing from the first one that took place at 776 BCE every 4 years.
