I guess I'm that person ...
The TNG/DS9/VOY era stardates are actually really easy to calculate: 1000 units per year, with 2364 = 41xxx (first season of TNG). TNG Season 1 was a bit of a mess with the stardates, but after that the remainder of that era is surprisingly consistent.
Assuming the screen caps are DS9 Season 5 or 6, that is either 2373 (50xxx) or 2374 (51xxx). The 1st of April for those years would span the following stardates (rounding to one decimal place):
1st April 2373: 50246.6 to 50249.3 1st April 2374: 51246.6 to 51249.3
For DS9 Season 4 (2372), it would be slightly different, being a leap year:
1st April 2372: 49248.6 to 49251.4
Yes, there is...
