School hours could change. And if you're far north enough, standard or daylight ain't gonna matter, there will be times when kids are walking in the dark.

You’re either walking to or from school in the dark in more northern places, it’s an irrelevant argument.

Shortest day of the year in my city is only 8 hours long.

Schools can choose to start later in the day if they find it helpful, without needing everyone else to change their clocks and schedules too

BC winter is dark and gloomy in the morning and dark again by 3:30. So this won't mean much for us, other than some actually usable daylight

That's caused (at least in part) by assigning timezones according to politics rather than longitude. Some places have gotten really skewed.

Anyway, most of us just want the government to pick one thing and stick with it. We don't care whether they pick DST, ST, or create a new half-hour timezone to split the difference so long as the changing back and forth stops.

The main reason it still exists is not a good one.

People are used to it happening and are scared of change.

I can assure you kids are going to school in the dark when we're on standard time. I was actually in grade school when the US stayed on DST year round for a hot minute in the 70s. It was no big deal
