Darkness arrives earliest on December 6 at 5:05 PM and latest on June 26 at 9:04 PM, a swing of 3 h 59 min across the year.
The longest day brings 14 h 59 min of daylight and the shortest just 9 h 21 min. The earliest dusk comes about 15 days away from the shortest day, because Earth's oval orbit shifts solar noon through the year.
