Stardates Explained - 20250719.0117

You don't understand the startdates?

Take, for example, 20250719.0117

Let me stick some spaces in some helpful places:

2025 07 19 . 01 17

That better?

20250719 means 19th July 2025, and 0117 is in 24-hour clock format, IE 1:17AM

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