Did You Know?
The Minoan eruption around 1600 BC was one of the largest in human history, ejecting perhaps 60 cubic kilometres of material and leaving the caldera the island now sits around. Akrotiri, buried by it, was preserved almost intact.
The clock: Santorini keeps UTC+2. Its sunsets from Oia are crowded enough that the town manages the viewing points.
Santorini lies at 25.4°E. Its time zone, UTC+2, is built around the 30°E meridian. The 4.6° gap between them means the clock runs roughly 18 minutes ahead of the sun: solar noon arrives at about 12:18 rather than 12:00. Under daylight saving the clocks move 60 minutes forward, widening the gap to 78 minutes and pushing solar noon to 13:18.
The longest day of 2026 is 22 June, with 14h 39m of daylight. The shortest is 22 December, with 9h 40m. The swing between them is 4h 59m. 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 Santorini the sun comes up earliest on 14 June at 05:59, while the latest sunset waits until 30 June at 20:40. 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 Santorini that civil twilight runs about 26 minutes at the equinox, stretching to 31 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.
