Enterprise 2015 LTSB Enterprise 2016 LTSB Enterprise 2019 LTSC Windows Server 2016 Windows Server 2019 what's strange in using year? i know it's released in 2018, but MS want to keep the 3 years threshold between regular Server releases Office as well
Nothing strange about that. I was confused as to why a 2019 label was used when we still have 2018, but you cleared that up nicely.
some famous products also is working like this for example coreldraw or autodesks products says almost all 2019 but the year is 2018 ..
