Question

What two-letter abbreviation used with a date (that is not CE) means how many yers after the binth of jesus christ something happened

Answer 1

AD - нашей эры (our era) (after Christ's birth)
нашей эры (Anno Domini)

До нашей эры (наречие) - BC (before our era), Before Сhrist  (до Христа)

Год нашей эры - AD ставится перед датой (AD1066), BC - после (300BC);
при указании столетия и то и другое идет после числительного (second century AD, fourth century BC).
