Sunrise & Sunset Clock

Use the clock above to estimate sunrise, sunset, solar noon, daylight length, and the next solar event for the current date and location. The main display stays focused on the result first, while location, time zone, seconds, and 12/24-hour settings stay below the active clock.

This page is useful when you want a quick daylight check without opening a full weather app or almanac. Choose device location or manual coordinates, and the display shows today's sunrise and sunset windows using the page's solar calculation model.

When to use this daylight clock

Use it for planning a walk, comparing daylight across locations, checking the next sunrise or sunset, estimating how much daylight remains, checking travel daylight for the current day, or giving a classroom astronomy demo about how daylight changes by season and location. It is designed for everyday planning and general daylight awareness, not for safety-critical navigation, aviation, marine use, or official almanac decisions.

• Outdoor planning: check whether sunset is before or after your walk, commute, practice, or casual outdoor schedule.
• Travel planning: enter destination coordinates and a matching time zone to understand roughly how much daylight that place has today.
• Classroom use: compare different latitudes or talk through seasonal daylight changes using the live result as context.
• Daily awareness: keep the next solar event visible when you simply want to know whether sunrise or sunset is coming up.

Location and time zone settings

Sunrise and sunset depend heavily on the selected coordinates. Device location uses browser geolocation when permission is available. Manual coordinates are useful when you prefer not to share location, when the browser cannot access it, or when you are planning for somewhere else.

The time zone field controls how the resulting times are formatted and which local date the page uses for today's live clock. Your device time zone is fine for a local check. If you are planning for another city or country, enter a matching IANA time zone such as Europe/Berlin, Asia/Tokyo, or UTC. For scheduled calls or travel comparisons, use the time zone converter after checking the daylight window.

• The date shown in the display comes from the live clock and selected time zone; this route does not include a manual date picker.
• The seconds and 24-hour toggles change the display format only; they do not change the solar estimate.
• Location permission is optional. If it is blocked, switch to manual coordinates.
• High-latitude places may have dates with no sunrise or no sunset, depending on the season.

Accuracy and practical interpretation

Results are estimates based on the coordinates, current date, time zone, and the calculation assumptions used by the page. Terrain, buildings, elevation, haze, and local horizon shape can change what you actually see outside. Treat the times as useful planning guidance, and check official or local sources when timing is critical.

If the page is left open, the clock updates from your browser and device clock. Background tabs, low-power modes, or sleeping devices can delay visible updates, though the display reconciles when the page is active again.
