On November 11, 2026, the Sun rises at 7:31 AM and sets at 4:46 PM in Frankfurt, for 9 h 15 min of daylight. Times are local time (UTC+1) and refer to the moment the upper edge of the Sun touches a flat sea-level horizon, with standard atmospheric refraction. Hills, buildings and unusual air temperature shift what you actually see by a minute or two.
Over 2026, the longest day in Frankfurt is June 21, with 16 h 23 min between sunrise and sunset, and the shortest is December 21, with 8 h 3 min.
Civil twilight, when the Sun is less than 6° below the horizon, is the half hour or so of usable light before sunrise and after sunset. The table gives the same figures for the next two weeks, so you can watch the days lengthen or shorten, and adds the Moon so you know whether it will light the evening.
