This section of the website has several utilities that are used by the logbook software to calculate times.

Sunrise Sunset Calculator calculates the sunrise and sunset for a specific date and location.

Airport Browser contains a list of airports used by the logbook software to lookup position to calculate sunrise and sunset.

Night Calculator used to calculate the night portion of a flight - given a start airport and time and an end airport and time, it will look up the latitude and longitude for both airports and the sunset and sunrise for those airports and compute how much of that flight was at night time.
