Notice days getting shorter in October? Here's how much daylight we've lost

We lose anywhere from 40 minutes to upwards of 90 minutes of daylight in Seattle and an hour and a half in Minneapolis

SEATTLE – You might have noticed that the days are getting shorter in October, and it could be a bit disappointing for some.

The amount of daylight quickly grows shorter as October progresses, with the fastest decrease at the beginning of the month. In total, anywhere from 40 to upwards of 90 minutes of daylight in Seattle and Minneapolis. 

There are 31 days in October, and we typically lose maybe a minute or two minutes for sunrise and sunset. The day is getting shorter and shorter. If you do the math, that’s an easy 60 to 70 minutes.

For some, the last 7 p.m. sunset of the year occurs in October, ushering in a five-month period in which the sun goes down before 7 p.m. It might take until early to mid-January to start slowly gaining morning daylight. In parts of the southern United States, the earliest sunset occurs more than a month before the latest winter sunrise.

It’s all about Earth's axial tilt. The speed with which you lose daylight hours depends on your latitude. The higher your latitude, the faster you lose daylight. 

Cities across the United States had their last 7 p.m. sunset of the year already. Atlanta saw its last 7 p.m. or later sunset on Oct. 17. Huston reached this milestone on Oct. 6.

Due to Daylight Saving Time, many parts of the U.S. will see the sunset around 6 p.m. on March 12, 2022, then around 7 p.m. on March 13 because of the one-hour time change.

And here's an interesting note: Everyone on the planet experiences an equal amount of darkness and daylight on the first day of spring and fall.
