In this comprehensive guide, we‘ll cover everything you need to know, from the official time zone designation to Daylight Saving Time and comparisons to other major cities. Let‘s get started!
San Antonio‘s Official Time Zone
San Antonio, Texas is officially in the Central Time Zone. According to the U.S. National Institute of Standards and Technology (NIST) and the Office of the Federal Register, the Central Time Zone has the following designation:
This means that San Antonio‘s time is 6 hours behind Coordinated Universal Time (UTC). For example, when it‘s 12 noon in San Antonio, it‘s 6:00 PM UTC.
During Daylight Saving Time, between mid-March and early November, the city follows Central Daylight Time (CDT), which is 5 hours behind UTC.
The Central Time Zone spans across the central regions of the United States and Canada, covering a total land area of around 1.6 million square miles and around 90 million people.

This gives you a sense of how the different time zones align across the continental U.S. It‘s useful when scheduling calls, online meetings, and travel plans between time zones.
Major Cities in the Central Time Zone

Some of the most notable cities that follow Central Time include:
So when it‘s 12 noon in San Antonio, it‘s also 12 noon in Chicago, Dallas, New Orleans and all the other cities above. Thisuniformity makes travel, trade, and communication much simpler across the region.

Daylight Saving Time in San Antonio, Texas
San Antonio observes Daylight Saving Time (DST) along with most other parts of Texas and the United States. Per federal law, DST begins on the second Sunday of March at 2 AM local time. On this date, San Antonio springs forward an hour to 3 AM.
DST ends on the first Sunday of November at 2 AM local time, when San Antonio reverts back to 1 AM. This fall-back transition marks the return to standard time for winter.
In 2023, Daylight Saving Time will start on March 12 and end on November 5 in San Antonio. The period when DST is active falls within the Central Daylight Time (CDT) zone, which is UTC-05:00.
When DST is not active between November and March, San Antonio follows the standard Central Standard Time, which is UTC-06:00.
Why Do We Have Different Time Zones in the US?
The Continental United States spans over 3,000 miles from east to west – which means there are wide differences in sunrise/sunset times and solar noon as you move across the country.
So time zones were established in 1883 to create uniform local times for communities based on their longitude. This allowed people to follow synchronized schedules aligned with the position of the Sun in their region.
The shift to Daylight Saving time was also introduced to make better use of daylight and conserve energy in the summer months.
Currently, the U.S. observes 9 standard time zones, along with 2 additional zones for overseas territories like Puerto Rico and the U.S. Virgin Islands. Neighboring Canada follows 6 time zones.
While technology allows us to communicate across time zones, local time still impacts our daily rhythms and routines in many ways.
Does Anywhere in Texas Follow Mountain Time?
Legally, no – the entire state of Texas is fixed to Central Time after changes made to time zone boundaries in the mid-1900s.
However, the extreme western areas of Texas bordering New Mexico like El Paso and Hudspeth County are geographically within the Mountain Time Zone. Some smaller towns and communities in this region unofficially observe Mountain Time due to their economic ties with southern New Mexico.
For example, the neighboring town of Santa Teresa in New Mexico is on Mountain Time, an hour behind El Paso. Many in the El Paso metro work, shop or go to school in Santa Teresa.
So while El Paso officially runs on Central Time, you may find some businesses and organizations following Mountain Time instead based on their links across state borders.
