Does the rate of change stay consistent . Do we pick up more sunlight per day right after the solstice or around the equinox?
At solstice, the change is pretty slow - only a few seconds per day.
But by the time equinox gets here, the change is the largest it will get - over 3 minutes per day.
Which doesn’t sound like a lot, but 3 weeks at 3 minutes per day is a bit more than an hour change of daylight.
These numbers are latitude related - the change at or near the equator is almost negligible.
