Darkness arrives earliest on December 7 at 4:56 PM and latest on June 26 at 9:04 PM, a swing of 4 h 8 min across the year.
The longest day brings 15 h 8 min of daylight and the shortest just 9 h 13 min. The earliest dusk comes about 14 days away from the shortest day, because Earth's oval orbit shifts solar noon through the year.
After sunset, twilight lasts about 27 min at the March equinox and stretches to 34 min in midsummer. Near the equator it is only about 21 min year-round.
In Greenwich, on 31 evenings it stays light until after 9 pm, while on 109 days it is dark before 6 pm.
Greenwich sits close to the middle of its time zone, so the sun is highest within 7 min of noon on standard time.
