Switch to summer time in IL: why we do it, how to adjust it

ILLINOIS — Whether you’re enjoying the extra hour of sunshine before settling in for the evening or dreading the twice-a-year ritual, daylight saving time begins on Sunday, March 13, almost everywhere in the United States.

Residents of 48 of the 50 states, including Illinois, will “move forward” — that is, put their clocks forward one hour to 2 a.m. — on Sunday, March 13. Hawaii and most of Arizona do not observe daylight saving time, having opted out of the Uniform Time Act of 1966, which mandated daylight saving time.

In Illinois, legislation providing for year-round daylight saving time passed the Senate in 2019, but failed to pass the House. Similar bills were introduced in January and February 2021. Bill 2946, introduced by Rep. Bob Morgan (D-Highwood) was referred to the House Rules Committee. House Bill 216, introduced by Rep. Adam Niemerg (R-Teutopolis), also went to the Rules Committee and chose an additional sponsor in Rep. Brad Halbrook (R-Pana).

Several bills — seven, to be exact — were introduced in Illinois last year to make DST permanent here or exempt Illinois from the federal uniform time law.

Full-time DST is currently not permitted by federal law and would require an act of Congress to make a change.

And although the “leap forward” is often associated with the onset of spring, the vernal equinox does not occur until the following Sunday, March 20. Daylight saving time ends this year on Sunday, November 6, when the clocks “fall”. one hour return.

In Arizona, where the temperature can regularly reach scorching 115 degrees, it’s all about keeping earlier sunsets and cooler evening temperatures. But the decision not to participate in the weather adjustment is not absolute in Arizona. DST is observed on the Navajo reservation, which surrounds the Hopi reservation, which is not.

Because Hawaii is far south of the mainland states, with a latitude similar to Mexico City, lawmakers saw no need to increase sunlight hours. The US territories of American Samoa, Guam, Northern Mariana Islands, Puerto Rico, and the US Virgin Islands also do not observe daylight saving time.

According to the National Conference of State Legislatures, at least 22 states have introduced legislation this year to switch to daylight saving time year-round, standard time year-round, or allow voters to decide the question. Another 18 have trigger laws on the books that would go into effect if Congress authorizes such a change.

Daylight saving time has existed since the First World War. But it became the law of the land more than 50 years ago with the Uniform Time Act of 1966, although the exact dates – now the second Sunday in March and the first Sunday in November – have changed some over the years. .

Who really benefits from the time change?

Proponents may argue that longer evenings motivate people to get out of the house. The extra hour of daylight can be used for outdoor recreation such as golf, football, baseball, running and more. This also benefits the tourism industry.

However, reviewers say the cons outweigh the pros. Daylight saving time can disrupt our biological clocks and circadian rhythms, leading to restless nights and sleepy days. It is also difficult to quantify the economic cost of collective fatigue caused by daylight saving time, but studies have found a decrease in productivity after the spring transition.
