Question: how do you calculate years between bce and ce?
Answer: Count the number of years between 4713 BCE and your current year. For example, if the date you're converting is in 2010, you want the number of years between 4713 BCE and 2010. 4713 BCE to 0 CE is 4713 years, and from 0 CE to 2010 is another 2010 years. 0 CE itself is also one year.
