# Why does the sun set later in Germany than in NY?

Why is it that, in Geneva, NY...(42.87 N) on June 28th, the sun set at 9:15 pm, whereas in Bielefeld, Germany (52.03 N) on the same day, it set at 10 pm?

(The former observed out my window, the latter observed simultaneously by me on webcam and by someone talking to me on Skype from Bielefeld).

Shouldn't it be the other way around?

The time of day is quite arbitrary and is set and changed by different countries to give people more sunlight hours - it's called daylight saving. In some countries different states at the same longitude will be on different times. Australia for example has two states that refuse to do daylight saving when everyone else does, sotyou change your watch as you go over the state line. Bielefeld's 'real' time was probaby 9pm.

During the summer, the days are longer at higher latitudes. In the extreme, at the poles, the day is 24 hours long during summer. At intermediate latitudes the sun rises earlier and sets later as you get closer to the pole.

At the equator the day is always 12 hours of sunlight and 12 of night regardless of the season.

It might help to understand this if you imagine a ball (better still, do this) in a dark room illuminated by a single light source. Put a mark on the ball to represent the north pole and tilt the ball so that this point is closer to the light; you have created summer in the northern hemisphere. Measure the angle around the ball, parallel to its equator, from the beginning of light to its end, i.e. from sunrise to sunset, and note that this angle is greater the closer you are to the north pole.

The earth is tilted with the north pole towards the sun (a 23.5 degree tilt). The farther north one lives, the later the sun sets until when you are at locations north of 66°34' N or south of 66°34' S latitude, the Sun will be above the horizon all day in the summer and below the horizon all day in the winter.

depends on the time of year; When the northern hemisphere is in winter, the sun sets earlier in Bielefeld Germany than it does in New York.

Germany is farther north so the summer days are longer. Another factor that comes into play is how far east of west in the time zone you are. The sun will set later toward the western edge of the time zone than the easter edge.

Maybe Geneva is further west within its time zone than Bielefeld is within its time zone.

As another example, both Dallas, TX and Lubbock, TX are in CST, but Lubbock is significantly further west, so when the sun sets in Dallas, it hasn't yet set in Lubbock.

you are able to understand that the earth revolves around it rather is N/ S axis yet that it fairly is tilted from the N/S vertical which might impression the time of solar set in distinctive places.you additionally can ask "why does the solar set so early in US while in comparison with Germany?"

Because it also rises later there.
