Most people seem to have a negative reaction to this, but I think we should all go UTC. Timezones are for suckers. My schedule at work is 4"pm" to 12"am," dinner is about 2, and sundown is currently about 3am.
Except when you have to work with people geographically separated. Trying to figure out when their work hours are UTC, and when yours are, so as to line it up. Boom, you've reinvented timezones by a different name.
Let's say the European goes to work at 8 o'clock UTC. The American in this example goes to work 6 hours later at 14 o'clock UTC. Both now exactly when the other one is in office. Time zones aren't needed here.
Time zones are an invention to keep the zero hour (for hour counting) at about the same local time - midnight. Midnight was easier to determine that UTC (or GMT). A peasant could do it in a day without the help of expensive tools everywhere on Earth. As a matter of fact almost each city in medieval times had its own local time. To get that sorted out they where clustered into time zones.
My company is fully remote. We use the working hours that people set on their calendar, because even people in the same time zone may not have the same working hours. My working hours start 30 minutes later than someone one timezone to my west.
Someone please ELI5 Daylight Savings for me? I simply can't wrap my head around it no matter how many times I try to read any explanation about it. I don't even know if my own region follows it (probably not given I would've understood it otherwise).
All this time I was wondering what black sorcery DST was performing to magically "add more sunlight" when it was simply the matter of setting the clock 1hr early.
I would rather go with having separate schedules for winter and summer for everything; even thinking about adopting DST is nauseating for me. I enjoy having a uniform time scale independent from external environmental factors.
Daylight savings time moves the clock to match sunrise and the time we wake up.
I live in the northern hemisphere and the days are shorter in the winter. The sunrise is 8 a.m. on the shortest day (December 21), while sunrise on the longest day (June 21) is 5:45 a.m.
If I'm a farmer and I get up for my chores at 5 a.m. everyday, it's nice and sunny in the warmer months. By the time it's October, I wake up well before the sun so I might as well wait another hour. Lots of people had the same idea. Eventually everyone agreed on a day, called it daylight savings time and figured moving the clocks by one hour was simple enough.
But now it's the 21st century, we have atomic clocks and most people live in the city but it's hard to break tradition.
It is a common myth in the United States that DST was first implemented for the benefit of farmers.[38][39][40] In reality, farmers have been one of the strongest lobbying groups against DST since it was first implemented.[38][39][40] The factors that influence farming schedules, such as morning dew and dairy cattle's readiness to be milked, are ultimately dictated by the sun, so the clock change introduces unnecessary challenges.[38][40][41]
TL:DR for the rest of the history and rationale: Most of this was rich people wanting more time for their personal hobbies, other people’s sleep and health be damned.
