Stardates Explained - 20191119.1900

You don't understand the startdates?

Take, for example, 20191119.1900

Let me stick some spaces in some helpful places:

2019 11 19 . 19 00

That better?

20191119 means 19th November 2019, and 1900 is in 24-hour clock format, IE 7:00PM

Stardates in the Star Trek universe work in an entirely different way. Wikipedia has a good explanation on how Stardates work.
