(NEXSTAR) — As the days become shorter — with some places losing over an hour of daylight in September — and leaves keep changing color, it also means a shift in our clocks is not far off.

Though numerous efforts have been made this year both at state and federal levels to keep clocks consistent, most parts of the U.S. are still expected to lose an hour of sleep next month. This year’s daylight saving time ends on one of its earliest possible dates, leading to earlier times for sunrise and sunset.

Health experts note that earlier sunrises and sunsets can have benefits, such as more exposure to sunlight and impacts on our sleep patterns. However, it also translates to heading out or returning from work (or sometimes both) under the cover of darkness.

Consider someone living in Chicago. On November 1, before daylight saving time ends, sunrise will be at 7:23 a.m. and sunset at around 5:45 p.m. The following day, sunrise will be about 6:25 a.m. with sunset at just before 4:43 p.m.

For those working until 5 p.m., the commute home will be post-sunset. This is a reality faced by millions across the U.S. for some period between November and March until daylight saving time begins again.

The table below shows just how different sunrise and sunset will feel before and after daylight saving time ends this year: 

In many states where these cities are located, legislators have attempted to establish either permanent daylight saving time or permanent standard time to stop these biannual changes.

Colorado, Florida, Louisiana, Tennessee, and Texas are among a handful of states that have passed legislation that would enact permanent daylight saving time, but they require Congress’s approval. 

Similar legislation was introduced in Alaska, Connecticut, Illinois, North Carolina and Ohio this year. Lawmakers in Michigan and Indiana considered legislation that would exempt their states from observing daylight saving time. Bills calling for permanent standard time were also brought forth in California, Nevada, and Wisconsin. New York has seen proposed legislation on both sides of the clock argument.  

Nearly every state has seen at least one piece of seasonal time change-related legislation brought forth this year. Congress has also considered four bills, but none have passed. 

For now, we’ll set our clocks back an hour on November 2, and set them forward again in March.
