# How to calculate the time for the solar disk to pass the horizon and transit's lines

(Asked by: username_0 on 2018-07-05)

For a given **date**, **longitude**, and **latitude**:

Popular apps and websites give the time when the sun's center or edge is on the horizon (i.e., the time of sunrise and sunset) or its transit (i.e., noontime), but I want to ask how to calculate the time needed for the **solar disk** to pass the **horizon's** line and the **transit's** line (preferably in c# or java)?
