KML Maps: Length Of Day On The First Day Of Fall
About Length Of Day On The First Day Of Fall ....
I thought we should put the old myth to bed -- on the first day of autumn that all of earth has the same length of day, and it's always 12 hours of daylight and 12 hours of darkness. That is not exactly true -- due to refraction of sunlight on the earth's atmosphere, almost all of the world has more then 12 hours of daylight. Towards the poles, you have around 12 hours and 10 minutes of daylight, while closer to the equator, you have more like 12 hours and 6 minutes of daylight. This interactive map will help you understand the length of day, and when to expect the sunrise and sunset on that day.
Helpful Hint: While I suggest you look on blog for a downloadable PDF Map, you should be able to print or save this map by clicking the print button on the map above.
