This is very much a geographically specific thing. At further latitudes I can assure you we wouldn't want to waste our previous daylight by sleeping then away!

Wouldn't this be messed up on longer days, like in summer when the sun rises at about 4 AM and sets at 9PM? Or similarly, winter when the days are really short

As an immigrant to lands with extreme seasonal changes in the amount of daily sunlight, this does not make a lot of sense to me...Same - I didn't move up North until my 30s. The sun technically goes down where I live, but I have twilight at "night" that is so bright that I can read outside without lighting. During winter, time is just as difficult to keep track of as the sun sets around 2:30-3:00pm: Most of your evening will be in darkness. As a bonus, I get occasional n

> The more serious problem may be that the sun doesn't shine 24 hours a day.Can someone in the Eastern hemisphere confirm this? ;-)

Ok, but any situation where you start your day with light in the mornings in winter in the North will necessarily mean that you end your day with darkness in the evenings. Whether we call the time the day starts "7AM" or "8AM" doesn't change this.The fundamental trade-off is: sunlight when you wake up and you're going to school/work, or sunlight when you're coming back from school/work? Unless you reduce the school/work day, this is unavoidabl

Me too! Issue is that different longitudes have different sunrise/sunset times, so I went with an arbitrary cut down the middle to get a rough idea of how people in other timezones are feeling right now (tired, close to dark, etc)

You do realise that DST doesn't actually add any daylight to the day, and that if you get far enough north it'll be dark in the morning even an hour later than usual, right? In fact, if you get far enough north the sun won't rise at all in the winter…

Being in the PNW I for one would rather the sun go down at 4 in the winter than 3. Losing an hour of sunlight at 10pm in the summer is ok for me. I have blackout shades specifically because the sun is up too late in the summer in the northern US.

I doubt that you wake up naturally with the Sun. Where I live the difference between Winter sunrise and Summer sunrise is about 6 hours. Most people keep more regular hours throughout the year.

There are two curves to account - sunrise and sunset. Daylight savings attempts to flatten one of those and not the other!
