Clock changes

Arizona (at least the part where this station is) does not change its clocks for daylight saving time, so sunset moves smoothly: 5:34 pm on Oct 31 and 5:34 pm on Nov 1, 2026.

Why the earliest sunset is not on the shortest day

At this latitude the sun sets earliest around Dec 3, about 18 days before the winter solstice, and rises latest around Jan 9, about 19 days after it. In December, solar noon slides a little later on the clock each day (about half a minute per day), which shifts sunsets later while the days are still getting shorter. More on the 2026 findings. Within a minute of that time from Nov 25 to Dec 11.

Sunset and 5 pm

At Tucson the earliest sunset (5:19 pm) is already at or after 5:00 pm, so the sun never sets before 5 pm here.

These times repeat almost exactly each year (in our checks the earliest-sunset clock time did not change by even a minute from 2025 to 2029). Computed by Earliest Sunset; how we calculate this. Your exact spot, hills, buildings and elevation can shift what you see; this is the time the sun’s upper edge touches the flat horizon.

Long, dark evenings mean more heating. Heat pump vs gas furnace, propane and oil: heating cost in Arizona (on our sister site PlugVsPump, from EIA prices).
