Cluj-Napoca, Romania • 46.77° N, 23.62° E

Sunrise & Sunset in Cluj-Napoca Today

Q: What is the exact solar noon in Cluj-Napoca?

Solar noon in Cluj-Napoca occurs when the sun crosses the local celestial meridian (23.62° E) and reaches its maximum angular elevation above the horizon. Because Cluj-Napoca operates on Europe/Bucharest, solar noon typically occurs around mid-day, adjusted for the seasonal Equation of Time.

Q: How does atmospheric refraction affect sunrise and sunset in Cluj-Napoca?

At latitude 46.77°, standard atmospheric refraction lifts the apparent image of the solar disc by approximately 34 arcminutes (0.566°). Combined with the sun’s 16 arcminute semidiameter, official sunrise and sunset are calculated when the center of the true solar disc is 90°50′ from the zenith.

Q: When are the golden hour shooting windows in Cluj-Napoca?

The morning golden hour spans the Sun’s climb from 0° to 6° elevation, with the evening window covering the reverse crossing. Its duration varies with latitude and season rather than lasting a fixed 60 minutes.

Welcome to the definitive solar ephemeris for Cluj-Napoca (Romania), situated at geographic coordinates 46.7712° N latitude and 23.6236° E longitude within the Europe/Bucharest timezone. Because Cluj-Napoca is positioned at mid-latitude coordinates, daylight duration fluctuates predictably throughout the solar year—reaching its maximum duration during the June solstice and its annual minimum near the December solstice.

All timestamps displayed below are computed using client-side spherical astronomy algorithms derived from the U.S. Naval Observatory Astronomical Almanac 2024 and the NOAA Solar Calculator, accounting for standard 34-arcminute atmospheric refraction and 16-arcminute solar semidiameter at sea level.
