This Government calculator is essentially an online Nautical Almanac, meant primarily for celestial navigators.  However, it can be a useful tool for identifying and locating celestial bodies at any time in the future or past, anywhere on the planet ("What was that bright star we were looking at last night?" or "How high will the moon be at midnight on Sunday?" or "Can Mars be seen in Hawaii tomorrow night?")

Hc is the height in degrees above the horizon, Zn is the True Azimuth. The other tabular values are of interest to  navigators and astronomers.
