Times Of Sunrise And Sunset

---

• The latitude of the relevant location. Since the whole of the contiguous states of the USA and most of the more densely populated areas of Canada lie well to the south of Britain, in the summer the sun rises later than in Britain and sets earlier than in Britain. In the winter, the sun rises earlier than in Britain and sets later than in Britain. These differences are greatest in the southernmost parts of the USA and at mid-winter and mid-summer. This is easily remembered by considering that in the Arctic the sun never sets in mid-summer and never rises in mid-winter.

• The longitude of the relevant location relative to its adjacent time zone boundaries.

• In the summer, whether the relevant location is in an area which observes Daylight Saving Time or not.

• In any specific location the sun's rays may of course be blocked at sunrise or sunset by nearby mountains. Stated times of sunrise and sunset assume a flat terrain.

The Sunrisesunset.com web site offers a very useful facility to generate a calendar of sunrise and sunset times for any one of numerous cities in the USA and Canada for any specific month. External link checked Feb-01.
