Stardates Explained - 20180123.2300

You don't understand the stardates?
Take, for example, 20180123.2300.

Let me stick some spaces in some helpful places:
2018 01 23 . 23 00

That better?

20180123 means 23rd Jan 2018, 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 they work.
