Question: is ad equal to ce?
Answer: CE stands for "Common Era" or, rarely "Christian Era." The word "common" simply means that it is based on the most frequently used calendar system, the Gregorian Calendar. ... In usage, AD precedes the date, while CE follows the date, whereas both BC and BCE follow the date—so, AD 1492 but 1492 CE, and 1500 BC or 1500 BCE.
