Often an episode of trek will open with the captain giving a star date. But then never seem to make sense, they sound like "Star date 2341.4"
So it's the year 2341, and it's the fourth month? or would that be the day?
I'm just confused as to how it works.
Word of God says, in the last film, Stardates were the Earth year-point-day (.1 - .365)
In the Original Series, stardates were random numbers. No order, no nothing.
Next Gen, DS9 and Voyager all used a complicated system based on the season and thousandths of a year.
