АНУ-ын Төлөөлөгчдийн танхим жилд хоёр удаа цаг өөрчилдөг тогтолцоог халах тухай хуулийн төслүүдийг хэлэлцэхээр бэлтгэж байна.
АНУ-ын Төлөөлөгчдийн танхим энэ долоо хоногт “2025 оны Нарны гэрлийг хамгаалах тухай хууль”-ийг хэлэлцэхээр төлөвлөж байна. Ерөнхийлөгч Дональд Трампын дэмжлэгийг авсан уг хуулийн төсөл нь зуны цагийн хуваарийг улс орон даяар байнгын мөрдөх зорилготой юм. Одоогоор Хавай болон Аризона мужууд цаг өөрчилдөггүй бөгөөд бусад мужууд хавар цагаа урагшлуулж, намар буцааж хойшлуулдаг уламжлалтай.
Үүнтэй зэрэгцэн Төлөөлөгчдийн танхимд “2026 оны Бидний хүүхдүүдэд зориулсан нарны гэрлийн тухай хууль”-ийг мөн хэлэлцэж байна. Энэхүү хуулийн төсөл нь стандарт цагийг байнгын болгохыг санал болгож байгаа боловч мужуудад зуны цагийн хуваарийг сонгох эрхийг олгох боломжтой юм. Хууль санаачлагч, Ардчилсан намын төлөөлөгч Мэри Гэй Скэнлоны үзэж буйгаар, жилд хоёр удаа цаг өөрчлөх нь хүүхэд болон өсвөр насныхны сэтгэцийн болон бие махбодийн хөгжилд сөрөг нөлөөтэй төдийгүй зам тээврийн осол, зүрх судасны өвчлөлийг нэмэгдүүлдэг байна.
Ерөнхийлөгч Дональд Трамп зуны цагийн хуваарийг байнгын болгох хувилбарыг илүүтэй дэмжиж байгаагаа илэрхийлжээ. Төлөөлөгчдийн танхимын Эрчим хүч, худалдааны хороо өнгөрсөн тавдугаар сард уг хуулийн төслийг 48-ын 1 харьцаатайгаар дэмжсэн байна. Одоогоор АНУ-ын 19 муж улс Конгрессоос эрх олгосон тохиолдолд зуны цагийн хуваарийг байнгын мөрдөх хууль тогтоомжийг батлаад байгаа юм.

The House of Representatives could soon vote on a bill that could leave states to decide what time it is.
This week, the U.S. House is set to vote on the Sunshine Protection Act of 2025. The bill has the support of President Donald Trump and would call for year-round daylight saving time. Daylight saving time kicks in in the spring when people “spring forward” and move the clocks ahead an hour. It ends in the fall with “fall back.” Right now, Hawaii and Arizona are the only states that don’t participate in daylight saving time.
The bill, which has had versions pass in the Senate, would make that summer time permanent. Trump and others have long called for the end of the clock-changing process.
That vote is different than the Sunshine for Our Kids Act of 2026 that is also in the House. That bill also calls for the end of clock changing, but to make standard time the permanent measure. That would make the winter-era clocks the common one across the U.S. However, that bill would allow states the option to implement permanent daylight saving time if they choose.
Bill sponsor Democratic Representative Mary Gay Scanlon said in a press release that switching between standard time and daylight saving time can pose risks to public health and safety, increase motor vehicle accidents, mood disorders and even cardiovascular events whenever the switch occurs.
“For decades, scientists and medical professionals have highlighted the detrimental mental and physical health impacts of twice-a-year clock changes, particularly on children and teens,” Scanlon said in a press release. “The Sunshine for Our Kids Act will not only help children and teens during the most important years for mental and physical development, but will also promote public health and safety in our communities.”
Scanlon also says that switching to standard time permanently would align with the body’s natural circadian rhythms.
A circadian rhythm is the pattern that a person’s body follows on a 24-hour clock and manages a person’s wake-sleep cycle, according to the Cleveland Clinic. Factors including light, food intake, stress and physical activity can all affect the circadian rhythm.
If standard time becomes permanent, summer sunsets would happen an hour earlier than they currently do in the summer. The sun would also rise earlier during spring and summer.
However, Trump has thrown his support behind the other bill that would make daylight saving time permanent.
Under that bill, the U.S. would see later sunrises and sunsets. In May, the House’s Energy and Commerce Committee approved the bill in a 48-1 vote.
“We are going with the far more popular alternative, Saving Daylight, which gives you a longer, brighter Day – And who can be against that – This is an easy one,” Trump said on Truth Social, referring to the bill.
The Sunshine Protection Act passed the Senate with unanimous consent in 2022.
Nineteen states have enacted legislation to make daylight saving time permanent if handed the power by Congress.
