A day, in local time.
Sunrise, sunset, and twilight depend on your location and date. Every result uses the selected place’s time zone, including daylight saving time where it applies.
Plan around the light.
Use the monthly sunrise and sunset table for a longer view, or check the golden hour page for morning and evening light windows. Weather and the local horizon can change what you see.
Does sunset mean darkness?
No. Twilight continues after sunset. Civil, nautical, and astronomical twilight describe progressively lower positions of the Sun below the horizon. The twilight page lists each boundary for your date.
Sunrise and sunset times today and tomorrow
The calculator opens on today’s date in the selected place. Today and Tomorrow mean the civil date in that location, not on your device: when it is already tomorrow in Sydney, the result says so. You can also type any date between 1 January 2000 and 31 December 2099.
Times are rounded to the nearest minute and formatted in the place’s IANA time zone. If an event falls on the neighbouring civil date, which happens near the International Date Line and around midnight sun, the result shows that date in brackets instead of silently mislabelling it.
What each sunrise and sunset time means
Sunrise is the moment the upper edge of the Sun appears at a flat, sea-level horizon, allowing for standard atmospheric refraction. Sunset is the moment that edge disappears. Solar noon is when the Sun is highest in the sky; it is rarely exactly 12:00 because clock zones span many degrees of longitude and the Sun runs a few minutes ahead of or behind mean time through the year. Daylight is the elapsed time from sunrise to sunset. The methodology page explains the assumptions.
Any place on Earth
Open Use coordinates to enter a latitude, a longitude and an IANA time zone such as Europe/Berlin. Coordinates do not choose a zone automatically, so pick the zone that the location actually keeps. Dedicated pages exist for New York, Chicago, Dallas and Seattle, and the city directory lists every starter location.
