The duration of twilight depends on the latitude and the time of the year. The apparent travel of the Sun occurs at the rate of 15 degrees per hour (360° per day), but sunrise and sunset happen typically at oblique angles to the horizon and the actual duration of any twilight period will be a function of that angle, being longer for more ...
The above relation implies that on the same day, the lengths of daytime from sunrise to sunset at and sum to 24 hours if =, and this also applies to regions where polar days and polar nights occur.
