 TWILIGHT

Twilight application

Twilight calculates twilight from sun and moon. This is useful when planning a voyage and specially when out in the wild, be it climbing, hiking or sailing, where twilight is an important feature, or when planning a voyage. If you are looking at the stars or hunting northern lights, best periods will be when there is complete darkness.

Twilight also calculates best orientation and solar energy for you solar charger ;-)

I wrote Twilight while waiting for the first sun after a long and cold winter on board of a sailboat in the Thule region, in northern Greenland. Enjoy :-)
