For years I've used an Excel calculator - and I actually can't remember if I put it together based on something or if I downloaded it holus-bolus (i think I'm getting Alzheimer's!! ETA: I didn't create it - I don't know who did, but it doesn't have "my" style of coding in it )). It falls down prior to 2323 (IIRC - it's on my home laptop and I'm at work at present), but for dates after that, it's pretty spot-on with TNG, DS9 and VOY era stardates.
From memory, I think it even correctly pegs the Hindu Festival of Lights date from the episode Date's Day.
I love the principle of the Julian Date sans the first 3 digits, but it tends to collapse when it comes to the TNG dates (I think the precursor to 2364 dates works out to 87, from memory). I guess you could modify it easily enough (again, using an Excel sheet), but I haven't tried it yet.

When you are dead, you don't know that you are dead. It is difficult only for others.
It's the same when you are stupid...
