I have children and I’ve never heard any arguments for DLS that make any sense.
Most of the time people conflate longer summer days with DLS.
The situation with dark mornings is winter not standard time.
My children are already waking to school in daylight this time of year prior to the switch to DLS.
As others have said. I would rather permanent standard time but I’ll take permanent DLS. Moving the clocks twice a year is insanity.
As far north as BC is winter just doesn't have enough daylight to think you can get everything done with sunlight. Maybe Arizona has enough - but they don't do daylight savings time (one of two us states)
