Stardates Explained - 20200303.2300

You don't understand the startdates?

Take, for example, 20200303.2300

Let me stick some spaces in some helpful places:

2020 03 03 . 23 00

That better?

20200303 means 3rd March 2020, and 2300 is in 24-hour clock format, IE 11:00PM

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