I recall many threads on this through the years. I don't have time to track down chapter and verse at the moments, but believe the outcome is - there was no year 0 ! i.e. the calendar went straight from -1 to 1. i.e. it is a nominal not an ordinal ... and you have to use special arithmetic to compute durations that span the change. > -----Original Message----- > From: Élie Roux <elie.roux@telecom-bretagne.eu> > Sent: Monday, 20 July, 2020 18:56 > To: Cox, Simon (L&W, Clayton) <Simon.Cox@csiro.au> > Cc: public-sdwig@w3.org > Subject: Re: OWL-Time extensions for Era > > As a side note, if the common era is an interval, when does it start? > beginning of year 1 of beginning of year 0? > > Some eras do start at year number 0 (like Kali Yuga), some at year number 1 > (most regnal years eras).
