Stardates have been very consistent since TNG with each season being one year starting with stardates beginning 41xxx being in 2364 with Encounter at Farpoint. Then dates starting 42xxx being 2365 and so on so the further through the seasons you go the stardates move up consistently.
And within each season the third, fourth and fifth digits also increase consistently as they progress through a calendar year.
It’s the writers not keeping track of what happened on particular stardates that’s the problem and with well known fan databases like Memory Alpha also making mistakes like stating stardates beginning 54xxx are 2378 when in fact they are 2377.
If the writers wanted to make these things consistent in the case of Homestead for example as it had already been established in First Contact when first contact was they could still have had the party but made something like Zefram Cochranes birthday.
These are the kind of things I notice when watching Star Trek. I tend to spot the continuity and filming mistakes but rather the in-universe plot holes.
Like when an episode makes a big deal about having to go AROUND something they forget they’re in space and could just as easily go above or underneath it instead.
Or the big plot hole in Voyager.
They say it would take 75 years to get home at maximum speed. But at warp 9.975 it would only take a little under 15 years and as we know from when Paris is being flown to the ship Lt Stadi states the ship has a “sustainable cruise velocity of warp factor 9.975”.
These things bug me. They don’t annoy me, just a few niggles I have.
