Stardates

Stardate System:

The Seventh Fleet has developed a simple method of creating fictional stardates.  Using stardates helps us keep the spirit of the 24th Century alive in our documentation.
It doesn’t directly translate the stardates used on the show (aka it is not cannon).
It only works with The Next GenerationDeep Space Nine and Voyager.  But it can be used to accurately convert a Gregorian calendar date into a ‘stardate’.
The Seventh Fleet method of calculating stardates is as follows: The year runs from September to August. September was chosen because that is when the new season of Star Trek would start.  Taking the lead from The Next Generation the ‘year’ is represented by the first two numbers.  The third and fourth numbers represent the month with the last two numbers (separated by a “.”) represent the day of the month. Thus April 1, 2011 is Stardate: 64040.1.
The following list breaks down recent years and what stardate they would begin with
