Seasonal Sun Milestones in Eagle Mountain
Eagle Mountain's 9 PM sunsets run from about June 15 to July 9 — 25 evenings in a typical year. The wider season of sunsets at 7 PM or later lasts 213 days, from March 9 to October 7. Even in midwinter, sunset here never falls before 5 PM on the clock.
Days in Eagle Mountain first reach 12 hours of daylight around March 17, a few days before the March equinox, and drop back under 12 hours after September 25. Days with at least 15 hours of daylight run from June 11 to June 30. Days with less than 10 hours of daylight run from November 14 to January 27 (75 days).
The Sun's rising point moves along the horizon too. Around the June solstice it rises in the ENE (58°) and sets in the WNW (302°); by the December solstice it rises in the ESE (121°) and sets in the WSW (239°). That is a 63° swing — worth knowing when choosing a west-facing viewpoint for a summer sunset or an east-facing window for winter morning light.
Dates use the 2025 reference year. Clock-time milestones near daylight-saving changes move with the second Sunday in March and the first Sunday in November.
Daylight Through the Year in Eagle Mountain
Eagle Mountain sits at 40.31°N, a mid-latitude position that gives it a balanced but noticeable seasonal rhythm. The difference between its longest and shortest day is 5h 45m.
On the summer solstice around June 21, Eagle Mountain receives 15h 3m of daylight — the longest day of the year. By the winter solstice around December 21, that shrinks to 9h 18m, the shortest day. At the spring and autumn equinoxes, day and night are nearly equal at about 12h 10m, as they are everywhere on Earth.
Sunset moves fastest around September, when it shifts by up to 1.7 minutes a day in Eagle Mountain, and barely moves for weeks around the solstices. See how sunrise and sunset change through the year for why.
The Sun's Path Over Eagle Mountain
Where the Sun sits in the sky over Eagle Mountain depends on the season, and the contrast between summer and winter is set by the city's latitude of 40.31°N. On the summer solstice the midday Sun reaches 73.1° above the horizon in Eagle Mountain, its highest point of the year. On the winter solstice the midday Sun only reaches 26.3°, 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 Eagle Mountain its seasons.

Earliest and Latest Sunrises and Sunsets in Eagle Mountain
It is natural to assume Eagle Mountain sees its latest sunset on the longest day of the year, but it does not. The latest sunset actually falls around June 27 at about 9:02 PM, while the earliest sunset comes around December 7 at roughly 5:02 PM — noticeably before the December solstice.
On the morning side, the earliest sunrise in Eagle Mountain is around June 14 at 5:58 AM, and the latest sunrise around November 1 at 7:58 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 Eagle Mountain
Eagle Mountain, Utah changes its clocks twice a year, and both changes are visible in this page's numbers. On the second Sunday in March, Eagle Mountain springs forward and the evening changes overnight: sunset jumps from about 6:28 PM on Saturday to about 7:29 PM on Sunday. The price is paid at dawn — sunrise slips from around 6:50 AM back to 7:49 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 6:25 PM to 5:23 PM in a single day — the abrupt start of the early-dusk season — while sunrise brightens from around 7:58 AM to 6:59 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 Eagle Mountain
For photographers in Eagle Mountain, Utah, 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 Eagle Mountain's local timezone.
Golden "hour" is a misnomer — its length in Eagle Mountain 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 36 minutes; near the June solstice, when the Sun rises and sets at a shallower angle, it stretches to roughly 41 minutes, and near the December solstice it lasts about 43 minutes.
See the golden hour guide and blue hour guide for how to plan a shoot around these windows.
Solar Energy Potential in Eagle Mountain
Under clear skies, Eagle Mountain, Utah receives about 5.1 peak sun hours per day averaged across the year — from roughly 1.9 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 Eagle Mountain sits at 40.3°N, a fixed, south-facing panel captures the most energy over the year when tilted at roughly 40° from horizontal — about equal to the latitude. If you adjust the tilt seasonally, flatten to about 25° in summer, when the Sun rides high, and steepen to about 55° in winter, when it stays low.
These are clear-sky upper bounds from Eagle Mountain's solar geometry, not a forecast; clouds, shading, and equipment lower real output. See what peak sun hours mean.
How Eagle Mountain Compares
Daylight in Eagle Mountain swings 5h 45m between the June and December solstices. The median across the 1,847 cities on this site is 5h 16m, so the seasons move the clock 29m further in Eagle Mountain than in a typical American city. By that measure Eagle Mountain ranks 628th of 1,847 nationally, and 32nd of the 39 Utah cities listed here — counting from the largest swing down.
Eagle Mountain sits about 7.0° west of 105°W — the meridian Mountain Time is built around. Longitude alone therefore puts mean solar noon roughly 28 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.
About Sun Times in Eagle Mountain
