1) When does daylight saving time end?Daylight saving time ends Sunday, November 3 at 2 a.m. when clocks will fall back one hour to 1 a.m. This means that sunrise and sunset times will be one hour earlier starting Sunday. It also means that there will be an extra hour to sleep Sunday morning. 2) Who is affected?Almost all Americans, except for those in Hawaii, most of Arizona and U.S. territories, will need to make sure their clocks move back an hour. Many electronic devices, such as televisions, computers and smartphones, will automatically move back. Non-digital clocks will need to be reset manually.3) Why is daylight saving time necessary?Depending on whom you ask, it is not. What daylight saving time does is shift an hour of daylight from the morning to the evening. Governments implemented daylight saving time as a measure to conserve energy. While Americans conserve some energy in the evening with more daylight, research has found that the benefit is negated by increased energy usage in the morning.4) Why not have daylight saving time year round?It has been tried before. Most recently, President Richard Nixon implemented year-round daylight saving time in 1974 as America was affected by an energy shortage. The act ended in 1975 as Congress established a standard practice for daylight saving time, allowing for winter mornings to have more daylight, so more people could go to work and school in the daylight.Also, the legislature in Florida approved year-round daylight saving time in 2018, but the proposal needs approval of Congress. Several other states are also considering petitioning Congress to eliminate daylight saving time.5) What is the history of daylight saving time?Many consider Benjamin Franklin as the inventor of daylight saving time, though he only suggested that Parisians wake up earlier to enjoy more of the daylight, and to conserve candle wax. According to the University of Washington assistant professor of economics Hendrik Wolff, Germany during World War I was the first nation to implement daylight saving time. The practice spread to America during World War II. The European Union voted earlier this year to end daylight saving time as soon as 2021. Member nations could decide to move its standard time up an hour, effectively making it daylight saving time year-round. 2340

A library book in Maryland is getting national attention after a little girl’s love for the book turned into its own story.Anita Vassallo, the acting director of Montgomery County Public Libraries in Maryland, loves a good story.This month, she read the children’s book The Postman for the very first time, after getting a copy of it in the mail.The person who sent the book: Mora Gregg, who checked the book out from the library back in 1946, when she was just 2 years old. Mora Gregg and her family moved to Canada before she could return it. While cleaning recently, she found the book she’s had all these years.“Probably when I was dusting the books and came across it and was rummaging a bit because it had slipped behind some other books,” Gregg recalls.After finding the neglected piece of her childhood, Gregg decided to return the book to the library 73 years later.“I’m not getting any younger and I didn’t want it to get thrown away or lost or anything to happen,” Gregg says.Gregg mailed the book back to the library with a note inside, joking how she refused to let it go because she loved it so much.The story provided a surprise ending to Vassallo, who also joked about the book’s return.“We don’t charge fines on children’s books, so no matter how old a kid’s book is when it comes back to us, there’s no charge,” Vassallo says. 1356

A group of demonstrators smashed through glass doors and stormed Hong Kong's government headquarters on July 1, the anniversary of the city's return to Chinese rule. The dramatic events marked a break from Hong Kong's peaceful protests around a controversial extradition bill.The core of mostly young activists were inside the Legislative Council building for hours before leaving late on Monday night. Inside, they spray-painted slogans in Cantonese on the walls of the legislative chamber, torn down portraits and raised a black banner, that read: "There is no way left," mounting an open challenge to China and the city's embattled Chief Executive, Carrie Lam.The protesters had used trolleys as battering rams to bust through the entrance, pry open metal shutters and occupy the site. They also set up barricades and opened a line of umbrellas in an attempt to hold the complex, but shortly after midnight, scores of riot police descended on the demonstrators, firing tear gas and using baton charges to disperse the crowd. It is not clear why police did not clear the building earlier.One young university student, who didn't want to be identified, said protesters felt they had no choice while the government refused to listen to their demands. "The government didn't do anything when two million people asked them to. This is why we're taking further action," he said.The government issued a statement condemning the "extremely violent" acts, saying the police would take "appropriate enforcement action to protect public order and safety."'Extremely violent' actsThe protestors' siege of the Legislative Council building was starkly different than a peaceful march just one street over, on the same day; there, tens of thousands of Hong Kong citizens carried signs calling for greater democracy and an end to the extradition bill.Monday is the 22nd anniversary of the semi-autonomous city's return to Chinese sovereignty. The date is marked annually with protests calling for greater freedoms.Protesters had hoped to block or interrupt an official flag raising ceremony marking the occasion, attended by Lam.The ceremony marked a rare public appearance for Lam, who was forced to publicly apologize for the introduction of the extradition bill last month which sparked public outrage. Protesters fear the extradition bill could be used to send residents to mainland China for political or business offenses.After mass protests, the bill was shelved, and Lam says there are no plans to restart the legislative process for now. However, protests have not stopped, amid calls to abandon the bill completely. Another march on June 16 attracted around 2 million people, according to organizers.Small demonstrations have targeted police and government offices, shutting them down and trapping police officers in their headquarters for hours.Many protesters are still angry over police use of tear gas and rubber bullets to force people off the streets on June 12, when protesters successfully blocked off the city's legislature and prevented lawmakers from debating the extradition bill.In her speech at the flag-raising ceremony Monday, Lam promised to "ease anxiety in the community, and to pave the way forward for Hong Kong."Beijing stands behind leaderWhile Beijing has stood by Lam, she is facing criticism from all sides for her handling of the crisis.Lam says the bill was her idea, not Beijing's, and she has taken responsibility for a rushed roll-out and failure to communicate with the public.Even much of the city's business community, traditionally conservative and unwilling to get too involved in politics, came out against the bill, and some pro-government figures criticized Lam for pushing it through the legislature against proper procedure.Lam justified that move as necessary in order to extradite a wanted murderer to Taiwan, but that justification was undermined by Taipei's statement 3922
