KML Maps: Length Of Day On December 21
About Length Of Day On December 21 ....
Today is the shortest day of the year. But in some parts of the state -- the most northernly latitudes in the state -- the day is particularly short. Massena gets only 8 hours, 46 minutes and 25 second of daylight between sunrise and sunset. The opposite is true the farthest south you get. The most southerly municipality in New York State is Staten Island, with 9 hours, 16 minutes and 17 seconds between sunrise and sunset. On the first day of winter, Massena has a full half hour less of daylight then Staten Island. Who would have ever thought there would be such a great difference between the most southern and most northern parts of New York State? Don't feel too bad for Massena, because people on the first day of summer at Robert Moses State Park north of the 45 parallel enjoy the most daylight of any part of our state.
Data Source: Center point of each town, fed into PHP's date_suninfo function to calculate sunset time.
