Seasonal Sun Milestones in Union City

Around the June solstice it rises in the ENE (61°) and sets in the WNW (299°); by the December solstice it rises in the ESE (118°) and sets in the WSW (242°). That is a 57° swing — worth knowing when choosing a west-facing viewpoint for a summer sunset or an east-facing window for winter morning light.

The Sun's Path Over Union City
Where the Sun sits in the sky over Union City depends on the season, and the contrast between summer and winter is set by the city's latitude of 33.59°N. On the summer solstice the midday Sun reaches 79.8° above the horizon in Union City, its highest point of the year. On the winter solstice the midday Sun only reaches 33.0°, sitting much lower in the southern sky and casting long shadows even at noon.
Those roughly 47 degrees separating the summer and winter midday Sun are exactly what give Union City its seasons.

Earliest and Latest Sunrises and Sunsets in Union City
It is natural to assume Union City sees its latest sunset on the longest day of the year, but it does not. The latest sunset actually falls around June 29 at about 8:53 PM, while the earliest sunset comes around December 4 at roughly 5:30 PM — noticeably before the December solstice.
On the morning side, the earliest sunrise in Union City is around June 12 at 6:28 AM, and the latest sunrise around November 1 at 7:57 AM. The equation of time and daylight saving pull these dates away from the solstices — explained in why the latest sunset isn't on the longest day.
How Daylight Saving Time Moves Sunrise and Sunset in Union City
Union City, Georgia changes its clocks twice a year, and both changes are visible in this page's numbers. On the second Sunday in March, Union City springs forward and the evening changes overnight: sunset jumps from about 6:41 PM on Saturday to about 7:42 PM on Sunday. The price is paid at dawn — sunrise slips from around 6:57 AM back to 7:56 AM, so mornings turn dark again just as they were brightening.
The reverse comes on the first Sunday in November, when clocks fall back: sunset drops from about 6:46 PM to 5:45 PM in a single day — the abrupt start of the early-dusk season — while sunrise brightens from around 7:57 AM to 6:58 AM.
Only the clock label shifts on those Sundays; the times above are for a typical year. More in how daylight saving time changes sunrise and sunset.
Golden Hour & Blue Hour Photography in Union City
For photographers in Union City, Georgia, the planner shows your selected date's morning and evening golden-hour and blue-hour windows. Choose Today, Tomorrow, or a date in the calendar; all clock times are calculated in Union City's local timezone.
Golden "hour" is a misnomer — its length in Union City depends on the season, because it lasts as long as the Sun takes to climb from the horizon to 6° (or descend back). Around the equinoxes it runs about 33 minutes; near the June solstice, when the Sun rises and sets at a shallower angle, it stretches to roughly 37 minutes, and near the December solstice it lasts about 38 minutes.
See the golden hour guide and blue hour guide for how to plan a shoot around these windows.
Solar Energy Potential in Union City
Under clear skies, Union City, Georgia receives about 5.6 peak sun hours per day averaged across the year — from roughly 2.7 in December up to 8.3 in June. One peak sun hour equals one hour of sunlight at full intensity (1 kW/m²), the standard unit for estimating solar panel output.
Because Union City sits at 33.6°N, a fixed, south-facing panel captures the most energy over the year when tilted at roughly 34° from horizontal — about equal to the latitude. If you adjust the tilt seasonally, flatten to about 19° in summer, when the Sun rides high, and steepen to about 49° in winter, when it stays low.
These are clear-sky upper bounds from Union City's solar geometry, not a forecast; clouds, shading, and equipment lower real output. See what peak sun hours mean.
How Union City Compares
Daylight in Union City swings 4h 28m between the June and December solstices. The median across the 1,847 cities on this site is 5h 16m, so Union City has a 49m gentler seasonal swing than a typical American city. By that measure Union City ranks 1386th of 1,847 nationally, and 30th of the 49 Georgia cities listed here — counting from the largest swing down.
Union City sits about 9.6° west of 75°W — the meridian Eastern Time is built around. Longitude alone therefore puts mean solar noon roughly 38 minutes after clock noon in standard time, so the Sun runs behind the clock here, which is why evenings hold light later than the time zone would suggest. The equation of time then moves true solar noon up to about 16 minutes either side of that through the year.
