Hello! Here is a web site for the NOAA sunrise / sunset calculator http://www2.arnes.si/~gljsentvid10/nebes_pod/vzhodsonca1.html CJ Beegle-Krause Physical Oceanographer NOAA Office of Response and Restoration Namba Takaya wrote: Dir Sir Are there any ways to know theoretical sunset and sunrise time of any location and orbit of the sun also? It must be silly question. However, I have been traveling and I realized the much difference of lighting time as the latitudes are different. So I wish to know how different there are among locations which must be important for the difference of marine productivity in latitude.
