As the calendar turns to October and the Chicago area experiences cooler temperatures and chilly nights, it's natural to wonder when Daylight Saving Time ends.

The annual rite of spring brings the area extra daylight at the end of the day, but the twice-yearly time change is just around the corner, meaning earlier sunsets as winter approaches.

Here's what you need to know:

When does summer time end?

According to the provisions of the Uniform Time Act, daylight saving time ends on the first Sunday in the month of November.

This year that date falls on Sunday, November 3rd and the clocks will go back one hour at 2am. While that means a bounce back sunset, it also means an extra hour of sleep, which is probably welcome news

What other milestones are coming up?

On October 17, daylight temperatures in the city will drop below 11 hours, and just two days later, on October 19, the sun will set before 6 p.m.

The earliest sunset of the year occurs in early December, setting at around 4:19 p.m. for several days before slowly receding over the course of the day throughout the month.

Sunrise will continue to occur later in the morning, meaning the city will see less daylight each day until Chicago reaches nine hours and seven minutes of daylight on December 21, slowly gaining a few seconds each day after that.

When is daylight saving time coming back?

Daylight saving time returns to the Chicago area on Sunday, March 9, the second Sunday in March.

At this point, the city will again have nearly 12 hours of daylight and sunset will occur shortly after 7 p.m
