Sunrise & Sunset

Today’s sunrise, sunset, and total daylight for your location.

Free to use, no sign-up required. Sunrise & Sunset is one of 198 tools built into Xenition, alongside a chat that can use them for you.

Shows today’s sunrise and sunset for your location, the hours of daylight between them, and where the sun sits on its arc right now. Useful for planning walks or photography.

How to use Sunrise & Sunset

  1. Set your location by city name or with “Use my current location”.
  2. Read the Now time, the current time in that place, and the sun’s marker on the arc from sunrise to sunset.
  3. Check the line under the arc: a percentage “of daylight” during the day, or “Nighttime” after sunset.
  4. Read the Sunrise and Sunset tiles and the Daylight total.

How it works

Sunrise and sunset come from the Open-Meteo forecast API for your coordinates in local time. Daylight is sunset minus sunrise, rounded to the whole minute and shown as hours and minutes. The arc position is the share of that span already elapsed by the place’s current local time, updated every 30 seconds, placed on a half circle whose top is solar noon.

Example

If sunrise is 06:30 and sunset is 18:45, Daylight reads 12h 15m. At 12:37 half of that span has passed, so the line reads 50% of daylight and the sun sits at the top of the arc.

Questions about Sunrise & Sunset

Is solar noon always 12:00?

No. Solar noon is halfway between sunrise and sunset, which shifts with your position in the time zone, daylight saving and the time of year.

Why does day length change so much near the poles?

The tilt of Earth’s axis means high latitudes swing between very long summer days and very short winter days, while places near the equator stay close to 12 hours all year.

Use it from chat

You do not have to open Sunrise & Sunset to use it. Ask Xenition in plain language and it runs the right tool, then carries the answer into whatever you are working on — a document, a spreadsheet, a deck.
