The Titanic sailed from Southampton on 10 April 1912, and around 700 of its roughly 900 crew came from the city. Some streets lost a resident from nearly every house.
The clock: Southampton keeps GMT and BST, and has a double high tide — the tidal pattern gives it an unusually long period of high water, which is why it became a deep-water liner port.
Southampton lies at 1.4°W. Its time zone, UTC+0, is built around the prime meridian (0°). The 1.4° gap between them means the clock runs roughly 6 minutes ahead of the sun: solar noon arrives at about 12:06 rather than 12:00. Under daylight saving the clocks move 60 minutes forward, widening the gap to 66 minutes and pushing solar noon to 13:06.
The longest day of 2026 is 22 June, with 16h 32m of daylight. The shortest is 22 December, with 7h 56m. The swing between them is 8h 36m. This is the latitude band where the difference between summer and winter evenings is most obvious.
The earliest sunrise and the latest sunset do not land on the longest day. In Southampton the sun comes up earliest on 18 June at 04:51, while the latest sunset waits until 26 June at 21:24. The equation of time is what separates them: the Earth's elliptical orbit and axial tilt move solar noon back and forth by several minutes over the year.
The sky stays usably light for a while after the sun goes down. In Southampton that civil twilight runs about 33 minutes at the equinox, stretching to 46 minutes at the solstice.
Every figure in this section is computed from the city's own latitude, longitude and IANA time zone using NOAA solar algorithms (Spencer, 1971), accurate to about ±2 arcminutes below 65° latitude.
