Stardates Explained - 20230505.0000

You don't understand the startdates?

Take, for example, 20230505.0000

Let me stick some spaces in some helpful places:

2023 05 05 . 00 00

That better?

20230505 means 5th May 2023, and 0000 is in 24-hour clock format, IE 12:00 midnight

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