Longest/shortest day

Doesn't the year fly-by quickly? It doesn't seem like that long ago that it was January and now we have reached the longest day of the year - the time when the Sun reaches its maximum declination. Of course whilst it is the longest day in the northern hemisphere, it is the shortest day in the southern hemisphere. For those of us in the north this means that the number of daylight hours will start to get less from now on.

APoD has a nice image of the Sun rising over Stonehenge taken this time last year.

Comments: Longest/shortest day

what date is the shortest day in scotland

Posted by carey on Thursday 14th Dec 2006 (19:04 UTC)

The shortest day in Scotland is the same as it is for all of us in the northern hemisphere (although it is shorter than it is for England). The date is is 22nd December this year.

As yesterday, (22nd Dec 06), was the shortest day; can you tell me how many hours of daylight we had and going forward to the longest day, how much does the daylight time increase each day for England?

Barry, this really depends on where you are as the daylight hours are less during winter the further north you go so the top of Scotland has different numbers of daylight hours to the south coast of England. The best thing to do to get sunrise/sunset times is to put your longitude/latitude into the US Naval Observatory's calculator (use Form B).

what is the shortest day in western Australia in 2007

Posted by henry on Wednesday 30th May 2007 (12:14 UTC)

Henry, using the US Naval Observatory's calculator (linked in the comments above) you can work it out. The shortest day in the southern hemisphere is the longest day in the northern hemisphere so in 2007 the shortest day for you in Western Australia is 21st June.

If the sun rises at 7.22am in London on the shortest day of the year, at what time does the sun set?
