    Although there are other, more elegant, ways to compute what you want, a simple and fast way to accomplish this is to go to the USNO website at:

    http://aa.usno.navy.mil/data/docs/celnavtable.php

    Then put in the date and location and an initial starting time and get the resulting Hc. Then iterate the time until you get the result you are looking for.

    My question is how can I calculate the time for specific Hc, position and day for the Sun? Let’s say at land there is a building and the altitude of the building is five degrees as seen from my position. When the sun will rise over the building?
