When Do the Clocks Change in Texas?

Time Zones in Texas

Texas is not on a single clock. It spans 2 zones, which is why two places inside the same state can be an hour apart.

Where the line falls. Only El Paso and Hudspeth counties are on Mountain Time. The line sits just east of El Paso, near the Culberson County border.

What Actually Changes: Sunrise and Sunset

The hour on the clock is not the part anyone notices. This is what the change does to daylight in Houston, comparing the day before with the day after.

The amount of daylight barely moves across those two days — roughly the same number of hours either side. What moves is where those hours sit: the clock change shifts them from the evening to the morning, or back again. Full sunrise and sunset detail for Houston.

What Stands Out About Texas

The clock runs well ahead of the sun here

In Houston solar noon falls at 1:08 PM, which puts the clock 68 minutes ahead of the sun. States near the western edge of their time zone get long, late evenings in summer and mornings that stay dark well past the start of the school run in winter. It is the same rule everywhere; Texas just sits at the far end of it.

The seasons barely move the daylight here

Houston sees 14h 04m of daylight at midsummer and 10h 14m at midwinter — a swing of only 3h 50m. This far south the argument for shifting the clock is much weaker than it is in the northern states, because there is far less seasonal daylight to redistribute in the first place.

One clock, 44 minutes of real difference

El Paso and Houston read exactly the same time, but they are 11.1 degrees of longitude apart — about 44 minutes of real solar time. The sun sets that much later at the western end of Texas than the eastern end, every single day, and no clock change affects it.

The Next Clock Changes in Texas

The next move is backwards, which is the one people notice: an hour more sleep, and sunset arriving before most of the working day is over. US clocks change on the second Sunday in March and the first Sunday in November. These are the next dates that rule produces for Texas, computed from the current time zone rules rather than a fixed list — if the rules change, these dates change with them.

The Two Halves of Texas

Right now the two sides of Texas are 1 hour apart. That gap holds all year, because both sides change their clocks on the same dates — they simply start from different offsets.

Why Texas Keeps the Clock It Does

El Paso is closer to Los Angeles than it is to Houston, and it keeps Mountain Time to match New Mexico and Ciudad Juárez across the border rather than the rest of Texas. Drive east out of El Paso and you lose an hour before you are halfway across your own state.

The practical consequence is that every time difference involving Texas shifts by an hour on Sunday, November 1, 2026. Anything recurring across that date — a standing call, an automated report, a flight connection — is worth checking, especially against places that change on a different date or not at all.

To check an exact gap on an exact date, use the time zone converter, or the meeting planner for a whole group at once.

Crossing the State Line

These neighbouring states are on a different clock from Texas today. A state border is the most common place to lose or gain an hour without expecting to.
