Year distribution of sunrise and sunset times in Gölcük, Kocaeli - 2026
The following graph shows sunrise and sunset times in Gölcük, Kocaeli for every day of the year.
Daylight Dawn & dusk (civil twilight) Night Solar noon
Earliest and latest sunrise and sunset in Gölcük
In Gölcük, the earliest sunrise of 2026 is on June 14 at 5:28 am, while the latest sunrise is on January 4 at 8:24 am. The earliest sunset is on December 7 at 5:33 pm, and the latest sunset is on June 27 at 8:36 pm.
Gölcük gets 5h 50m more daylight on the longest day than on the shortest one (15h 05m versus 9h 15m). Averaged over the whole year, a day lasts 12h 12m.
Gölcük Analemma
Due to Earth's tilted axis and slightly elliptical orbit, the Sun is never seen in the same position at noon in Gölcük. Throughout the year, it slowly traces this figure-eight:
Move along the curve to read the Sun's altitude and azimuth for any day of the year in Gölcük.
Over the year, the 12:00 Sun swings between just 24.4° above the horizon (around Dec 26) and 68.4° (around Jun 17) in Gölcük. The smaller loop sits at the top, the signature of a Northern Hemisphere analemma. Notice the whole figure leans east of the meridian: over Gölcük the Sun reaches its highest point between 12:44 and 13:14 depending on the time of year, but never at 12:00.
Detailed Analemma Chart
The technical chart below plots one dot per day, labels the first day of each month, marks the solstices, equinoxes, perihelion and aphelion, and draws the noon altitude of the equinoxes (90° minus your latitude) together with its ±23.4° seasonal limits.
Why does the figure look wider here than in the sky view above?
Both draw the same data, but with different conventions. The sky view uses the same scale on both axes, so it shows the analemma with its true proportions, as a camera would capture it: about 47° tall and only a few degrees wide. This chart, like most technical analemma diagrams, stretches each axis independently to fill the plot, expanding the narrow azimuth range several times so its day-to-day variation can actually be read. Also, azimuth is not sky distance: near the zenith, one degree of azimuth spans much less than one degree across the sky, which further widens the figure in this representation.
