Stardates Explained - 20250505.0000

You don't understand the startdates?

Take, for example, 20250505.0000

Let me stick some spaces in some helpful places:

2025 05 05 . 00 00

That better?

20250505 means 5th May 2025, 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.
