ANSWER TO, IS 2019 THE END OF THE DECADE

The argument is that because there is no year 0 in the Anno Domini system our calendars are based on, the first year ever was year 1. Therefore, the first year of any and all subsequent decades is the one ending in 1. ... 2019 is not the end of the decade,

 2020 is.
