London, Westminster · —
Precise astronomical times. Sunrise, sunset and twilights are computed from the town’s coordinates (NOAA algorithm), with daylight saving included. Everything runs in your browser, no account, no data sent.
From the town’s coordinates (latitude, longitude) and the chosen date, the Sun’s position in the sky is computed. Sunrise and sunset are when the Sun’s centre is at −0.833° to the horizon, and dawn/dusk at −6° (civil), −12° (nautical) and −18° (astronomical):
In Bucharest, on 10 July 2026, the Sun rises around 05:41 and sets at 21:02 — a day of over 15 hours. Pick another town or date for your own times.
Pick the country, region and town; the date defaults to today. The calculator instantly shows sunrise and sunset, plus the twilights, computed from the town’s geographic coordinates.
They are the twilight phases, defined by how far the Sun is below the horizon: civil (down to −6°, you can still read outside), nautical (−6° to −12°, the sea horizon is visible) and astronomical (−12° to −18°, the sky becomes fully dark).
From the town’s latitude and longitude, the date and the Sun’s position (declination and the equation of time). Sunrise and sunset are taken at −0.833° below the horizon, which accounts for atmospheric refraction and the radius of the solar disc.
Because of longitude (more easterly towns see the Sun earlier) and latitude (which changes day length with the season). That is why sunrise in Iași differs from Timișoara by a few minutes.
Yes. Times are shown in the town’s real time zone (IANA, e.g. Europe/Bucharest), which automatically includes the switch to summer and winter time, so the result is correct at any time of year.
It is the moment the Sun reaches its highest point in the sky. It does not coincide with 12:00 on the clock: it shifts with longitude and the equation of time, sometimes by 15–20 minutes.
The longest day is at the summer solstice (around 21 June) and the shortest at the winter solstice (around 21 December). In Bucharest the day ranges from about 9 hours in winter to over 15 hours in summer.
It is the short window just after sunrise and before sunset, when the light is warm and soft. It starts roughly at sunrise / ends at sunset and lasts until the Sun climbs to about 6° — close to civil twilight.
