[Star Trek] How does the "stardate" calendar work? In the captain's logbooks, it really seems like they just rattle off random numbers for their entries.

Originally a stardate was a random selection of numbers, plus a percentage point. This has now been changed to a working and useful system, which is the year followed by the day. Today's stardate (in AEST) would be 2015.343.
