How many year are there between 200 BCE and 2000 CE?

Answer 1

Assuming that BCE is a renaming of BC and CE is a renaming of AD of the calendar devised by Dionysius Exiguus in 247 Anno Diocletiani which he designated 531 AD since he calculated that Jesus was born 531 years earlier, becoming his year 1 AD, which was preceded by 1 BC as zero was not invented for another 500 years or so, then between 200 BCE and 2000CE there are the 199 years 199 BCE to 1 BCE and the 1999 years from 1 CE to 1999 CE, making a total of 199 + 1999 = 2198 years between 200 BCE and 2000 CE (exclusive).

However, as people were celebrating 2000 CE as the start of the third millennium CE, the second must have run from 1000 CE to 1999 CE and thus the first must have run from 0 CE to 999 CE which means that in the BCE/CE calendar there is a year 0, which means between 200 BCE and 2000 CE there is an extra year, meaning there are 2199 years between 200 BCE and 2000 CE (exclusive).

Which dates have been corrected for this extra year in the BCE/CE calendar over the BC/AD calendar I would love to know; for example, Julius Caesar was assassinated on 15 March 44 BC, so is that 15 March 43 BCE?
