Now let‘s explore why the time zones differ in more detail.

Why Texas and California Have Different Time Zones

The Continental United States spans four major time zones. From east to west, they are:

• Eastern Time Zone
• Central Time Zone
• Mountain Time Zone
• Pacific Time Zone

Each time zone is approximately 15° longitude apart. This corresponds to a 1 hour time difference for every 15° as the earth rotates.

Texas is in the Central Time Zone which covers the mid section of the US. California is in the Pacific Time Zone in the far west.

During daylight saving time from March-November, Texas shifts 1 hour ahead to join the Pacific time, making it only 1 hour ahead of California.

Here is a map showing the 4 time zones:

When Daylight Saving Time Starts and Ends

• In 2023, daylight saving time begins on March 12 at 2AM when clocks spring forward 1 hour.
• It ends on November 5, 2023 at 2AM when clocks fall back 1 hour.

Texas switches from CST to CDT during the daylight saving period. Meanwhile, California remains on permanent Pacific Time all year.

Examples of the Time Difference

Let‘s look at some examples to make the time zone difference clear:

• During standard time in November:
  • 8 AM in Los Angeles is 10 AM in Dallas
  • 5:30 PM in San Francisco is 7:30 PM in Houston
• During daylight saving time in March:
  • 8 AM in San Diego is 9 AM in Austin
  • 11:30 AM in LA is 12:30 PM in Dallas

So in summary, Texas is 2 hours ahead during standard time, and 1 hour ahead during daylight saving.
