    Overview

    Plan Natural Light Without an API or Account

    This sunrise and sunset time calculator estimates sunrise, sunset, solar noon, daylight duration, civil twilight, nautical twilight, and astronomical twilight for a selected city, date, latitude, longitude, and display time zone.

    The page is built for people searching for sunrise time today, sunset time today, a daylight duration calculator, or a quick way to check twilight before outdoor work, photography, hiking, travel, aviation study, astronomy planning, and event scheduling.

    Competitor research showed that strong tools usually include city lookup, coordinates, solar noon, twilight phases, and a visible daylight timeline. This version keeps those useful pieces while staying privacy-focused: the static solar math runs in your browser after the page loads.

    Why Use a Browser Sunrise Calculator Instead of Manual Tables?

    Manual sunrise tables are useful, but they can be slow when you need multiple cities, coordinates, and twilight phases.

    TaskRandomly.onlineManual method
    Sunrise and sunset timeCalculates the selected date and location instantly.Requires finding the right table or city page.
    Daylight durationDisplays hours and minutes directly.Usually requires subtracting sunset from sunrise.
    Twilight phasesShows civil, nautical, and astronomical events together.Often requires separate references.
    CoordinatesSupports latitude and longitude without an account.Manual lookup is slower and easier to mistype.
    Guide

    How to Use Sunrise & Sunset Time Calculator

    Use city search for speed, or coordinates for precision.

    Choose a city or coordinates

    Search a city such as New York, London, Tokyo, Delhi, or Sydney. If you need a specific beach, trail, observatory, or job site, enter the latitude and longitude manually.

    Select the display time zone

    The calculator maps city presets to time zones, but you can search and choose another display time zone when planning travel or remote coordination.

    Pick the date

    Use Today, Tomorrow, Summer solstice, Winter solstice, Equinox, or the calendar field. The sunrise, sunset, daylight duration, and twilight list update locally.

    Read the timeline and copy results

    Use the daylight bar to understand dawn, daylight, and dusk visually. Copy the summary when you need to share sunrise time, sunset time, solar noon, or day length.

    Frequently Asked Questions

    How do I find sunrise and sunset time for my city?

    Search the city name, confirm the mapped time zone, and choose a date. The calculator shows approximate sunrise time, sunset time, solar noon, daylight duration, and twilight events.

    Can I calculate sunrise and sunset by latitude and longitude?

    Yes. Enter any latitude from -90 to 90 and longitude from -180 to 180. This is useful for remote places, travel stops, beaches, farms, observatories, and outdoor job sites.

    What is civil twilight?

    Civil twilight is the bright twilight phase before sunrise and after sunset. It is commonly defined around the point where the sun is 6 degrees below the horizon, which is why many users search for a civil twilight calculator.

    What is nautical twilight?

    Nautical twilight is the phase between civil twilight and astronomical twilight. It is traditionally associated with the period when the horizon is still relevant for navigation, and it is listed here as part of the full twilight timeline.

    What is astronomical twilight?

    Astronomical twilight is the deepest twilight phase before full night or after night begins. Stargazers search for astronomical twilight time because darker skies are usually better for observing faint objects.

    What is solar noon?

    Solar noon is the time when the sun is highest in the sky for that location on that date. This calculator estimates it from the midpoint between sunrise and sunset.

    Does daylight saving time affect the result?

    The displayed time depends on the selected IANA time zone. If that time zone observes daylight saving time on the selected date, the browser time formatter applies that offset.

    Why are sunrise and sunset times approximate?

    Sunrise and sunset depend on atmospheric refraction, local terrain, elevation, weather, and the exact horizon. This browser tool gives a practical static estimate, not an official almanac result.

    Can I use this as a daylight duration calculator?

    Yes. The day length card shows the approximate duration between sunrise and sunset in hours and minutes, which covers searches for day length calculator and daylight hours calculator.

    Can I compare solstice daylight?

    Yes. Use the Summer solstice and Winter solstice presets to compare long-day and short-day patterns for the selected city or coordinates.

    Does this tool need an internet API?

    No. After the page loads, the calculation runs in your browser. It does not upload your coordinates or selected city to Randomly.online servers.

    Can I copy sunrise and sunset results?

    Yes. Use Copy summary to copy the selected location, date, sunrise, sunset, daylight duration, and solar noon into messages, notes, travel plans, or schedules.

    Is this useful for photography or golden hour planning?

    It helps with first-pass photography planning because sunrise, sunset, and twilight tell you when natural light changes. For strict golden hour timing, use these values as a planning baseline and adjust for local terrain and weather.

    Why do high-latitude places sometimes show no sunrise or sunset?

    Near polar regions, some dates can have midnight sun or polar night. When the sun does not cross the horizon in the usual way, the calculator marks the event as polar/no event instead of forcing a normal time.
