My timeframe there is a big arbitrary and probably too extreme and does "miss the point" a little for DST.What is the point if we are going to have DST on the shortest day of the year (~20-22 DEC)?
Maybe better is something like late April (which is was for a few years, then gradually shifted up to the current March changeover) then switch to standard maybe closer to end of November.
The main thing I don't like with the clock shift is it feels like an unnatural change with cadence of daylight, for lack of better description. Less and less daylight gradually in fall, you kind of absorb the decrease, then overnight "darkness" goes from like 6:30 p.m to 5:30 p.m.
Maybe if it changed a few weeks later, the early evening hours already are "dark" no matter what. Or maybe it wouldn't.
