AD/BC, BCE/CE?

In my class, I always have to correct the misconception that when talking about years, 'AD' does not stand for 'after death' (it actually stands for anno Domini, which means Year of Our Lord in Latin). We work a lot with years that are both BC and AD in Asheklon, but I have also heard archaeologists refer to years at 'BCE' or 'CE'. I decided to ask one of our square supervisors, Laura, to explain how archaeologists use different phrases to measure time and if there were any other ways that years could be represented. Check out what she said!
