Sunrise Sunset Calculator | Find Vedic Sunrise and Sunset Times

Formula: cos(H) = cos(90.833°)⁄(cos φ · cos δ) − tan φ · tan δ

The Sunrise Sunset Calculator (Vedic) is built on a well-established calculation method. It uses the formula cos(H) = cos(90.833°)⁄(cos φ · cos δ) − tan φ · tan δ to turn your inputs into a reliable result. A Sunrise Sunset Calculator (Vedic) helps calculate sunrise sunset calculator vedic using Vedic astrology, panchang, calendar, muhurat, Vastu or naming inputs. It gives an instant browser-based result with a transparent The steps are shown on the page so you can follow the reasoning from input to output.

1. Enter the date you want sunrise and sunset for.
2. Enter the latitude (+ north) and longitude (+ east) of the location.
3. Set the UTC offset in hours, or leave it blank to use your device setting.
4. The NOAA solar-position algorithm returns sunrise, solar noon, sunset and day length.

Example: New York (40.71, −74.01) on 21 June 2026 (UTC−4) gives sunrise 5:25 AM, solar noon 12:58 PM, sunset 8:31 PM — about 15 h 6 m of daylight.

How to use the Sunrise Sunset Calculator

Enter your location — by address or latitude and longitude — and a date, and the tool computes sunrise, sunset, solar noon, and day length. It solves the sun's hour angle with cos(H) = cos(90.833°)⁄(cos φ · cos δ) − tan φ · tan δ, where φ is your latitude, δ the solar declination for the date, and 90.833° the zenith angle that accounts for atmospheric refraction and the sun's radius. The UTC offset you enter converts the solar time into your local clock time, including daylight saving.

Interpreting your result

Solar noon is the moment the sun crosses your meridian at its highest point — halfway between sunrise and sunset in solar time, though rarely at exactly 12:00 clock time because of longitude and the equation of time. Day length changes with latitude and season: near the equator it stays close to 12 hours year-round, while high latitudes swing dramatically between summer and winter. In the Vedic context these times anchor panchang computations and muhurta windows. The calculator is also practical for photographers planning golden-hour shoots, gardeners timing watering, and commuters scheduling drives.

Common mistakes to avoid

The most common error is entering the wrong UTC offset — an hour's error shifts every result by an hour, and daylight-saving time is the usual culprit. Second, using the wrong coordinates: sunrise times are sensitive to longitude for the clock conversion and to latitude for the geometry. Third, forgetting that sunrise and sunset are defined by the top edge of the sun crossing the horizon, not the center, which the 90.833° zenith angle accounts for. Finally, entering a date in the wrong format or timezone-aware vs naive dates — the tool expects a specific date and location pairing.

Tips for best results

Use your precise coordinates rather than a nearby city for accurate times — a 0.5° longitude error shifts sunrise by about 2 minutes. Remember to switch the DST offset for the date you are checking, since offsets change twice a year. For photography, plan around the golden hour, which starts roughly 30–60 minutes before sunset. For prayer or muhurta purposes, verify the calculation method matches your community's standard — different twilight angles shift Fajr and Isha times. Recalculate whenever you travel to a different time zone or longitude.
