Each column is one day from sunrise to sunset in local clock time. The one-hour steps are the daylight saving time changes.

The longest day in 2026 is June 21 with 14 h 06 min between sunrise at 6:29 AM and sunset at 8:35 PM. The shortest is December 21 with 10 h 12 min. The difference, 3 h 54 min between June 21 and December 21, ranks 50th largest among the 51 capitals. Few capitals see less seasonal change, because day length varies less closer to the equator.

Earliest sunrise and latest sunset

The earliest sunrise of the year comes on June 5 at 6:28 AM, and the latest sunset on June 22 at 8:36 PM. The latest sunrise falls on March 8 at 7:48 AM, and the earliest sunset on November 25 at 5:30 PM.

Clocks change on March 8 (to CDT) and November 1 (to CST), which moves every clock time by an hour. The earliest sunrise and latest sunset still fall days away from the longest day, because solar noon drifts through the year.

Solar noon and the time zone

On standard time Austin's clocks run 6 hours behind UTC, which matches the meridian at 90° W. The capitol sits at 97.74° W, 7.74° west of it, which puts the sun about 31 minutes behind the zone's clock noon. Solar noon on January 15 is at 12:40 PM and on July 15 at 1:37 PM; the rest of the gap comes from daylight saving time and the equation of time.

Compared with neighboring capitals

Day length depends on latitude, so capitals to the north get longer June days and shorter December days. Among neighbors, Santa Fe gets the most June daylight, 29 minutes more than Austin on June 21.
