【☀️ #我們不熟悉的日光節約時間將可能成為美國的日常】 今年7月14日，美國眾議院以308票贊成，117票反對的比數，通過「 #陽光保護法案 Sunshine Protection Act」🙋🏻，未來如果順利完成參議院同意，並被美國總統簽署，會讓日光節約時間(Daylight Saving Time)可以永久化🌞，也代表著美國大部分地區將全年實施夏令時，而不是像往年那樣每年秋季切換回標準時間。
目前美國本土大多數州，都奉行當地時間每年3月第2個週日凌晨02:00，自動切換至03:00，當日會少1小時，讓早晨的日光移到傍晚，晚上的天黑時間延後🌃；到了11月第1個週日02:00反向進行，倒回至01:00，這天就會多1小時，天黑時間就會提前發生。這項做法已有百年歷史，最早由歐洲的德國與奧匈帝國於 1916 年率先採用，隨後英美等國也紛紛跟進以節約能源，目前全球仍有約 70 個國家實施中。
這不是美國首次嘗試推動永久 #日光節約時間，20世紀時因為戰爭、能源危機等重大事件時也曾短暫實施，最近一次，發生於2022年參議院以無異議同意方式通過類似法案，後來因為眾議院未審理而失效。本次再度進入立法程序，雖然仍然存在支持與反對兩派聲音，讓法案最後的結局充滿了變數，不過此一法案推進也表示社會上存在高度需求，未來可能終究就成為正式法律。
不過法案一樣保有彈性，美國各州有權選擇使用永久日光時間，或是永久標準時間。未來如果實施，美國本土各地最晚的日出時間，將會是北達科他、懷俄明州的9:28，也就是大家如果仍是上午8至9點上班上課，有可能一年中一段時間得摸黑出門囉！
其實臺灣以前曾施行日光節約時間(夏令時間)，這段歷史將來再來分享唷！
#地圖新鮮事 #夏令時間 #3月有一天上班特別沒精神 #11月有一天夜店生意特別好
On July 14, 2026, the U.S. House of Representatives passed the Sunshine Protection Act by a vote of 308 to 117. If the proposal eventually becomes law, most of the United States would remain on Daylight Saving Time year-round instead of switching back to Standard Time each fall. The bill still must pass the Senate and be signed by the president before it can take effect.
Keeping clocks one hour ahead during winter would shift both sunrise and sunset about an hour later. That means brighter evenings, but also much darker mornings. In some northern and western parts of the country, the latest winter sunrise could occur after 9:00 a.m., while even many eastern states would not see the sun until well after 8:00 a.m.
The impact varies because of both geography and time zones. States located farther north receive fewer hours of daylight during winter, while places on the western edge of a time zone experience later sunrises than those on the eastern edge. When these two factors combine, sunrise can be pushed surprisingly late into the morning.
This is not the first time the United States has considered permanent Daylight Saving Time. The country briefly adopted it during World War II and again during the 1973 energy crisis. However, concerns about dark winter mornings, especially for schoolchildren, led Congress to end the experiment early.
The times shown on this map are approximate estimates of the latest sunrise that could occur within each state under permanent Daylight Saving Time. If the proposal becomes law, millions of Americans would gain more evening daylight in winter, but many would also begin their day before sunrise for a much larger part of the year.
Would you rather have brighter evenings year-round, or keep brighter winter mornings?
