Noticing later sunrises

It happens every year, and every year it surprises me: from mid-August to mid-October, the days get shorter quickly. Three weeks ago I was waking up to daylight; this morning, I realized I was waking up to twilight. In three weeks it'll be dark at that hour. Right now, every day, the sun rises a minute later an sets a minute earlier.

Nothing profound or particularly surprising here. Just an observation.
