1 BCE, then 1 CE.
In Julian and Gregorian calendars, which are outdated standards. In astronomical years there is a year 0. Doing some more research I may have been mistaken to append CE on, as it seems polarity notation has become vastly more popular.
Sure. But we're talking about decades, which is relevant primarily to the calendar system, not to astronomical dating methods. Even if we used astronomical dating though, year 0 is equivalent to year -BCE. It does not affect dates moving forward. Only those going backward.
I do agree however, that in popular usage we tend to think in terms of intervals of time. A decade is a 10 year period of time, a century is a 100 year period of time, etc. Counting starting at the zero is just as valid as counting by starting at the 1 and most people tend to associate dates in this manner. We think of the "80s" as those years in which the tens place contains an 8. This means the years from 80 to 89, not 81 to 90.
Traditional calendar dates are counts starting at "1" though.
