Stardates Explained - 20250808.1548

You don't understand the startdates?

Take, for example, 20250808.1548

Let me stick some spaces in some helpful places:

2025 08 08 . 15 48

That better?

20250808 means 8th August 2025, and 1548 is in 24-hour clock format, IE 3:48PM

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