San Antonio (Central Time, CT) and Barcelona (Central European Time, CET/CEST) are separated by 7 hours for most of the year.
| Period | San Antonio | Barcelona | Difference |
|---|---|---|---|
| Standard Time (Nov–Mar) | CST (UTC−6) | CET (UTC+1) | 7 hours |
| Daylight Time (Mar–Oct/Nov) | CDT (UTC−5) | CEST (UTC+2) | 7 hours |
Because both regions observe daylight saving (though on slightly different schedules), the offset remains a consistent 7 hours. When it's 12:00 PM in San Antonio, it's 7:00 PM in Barcelona.
Verify exact dates each year, as the EU and U.S. switch dates can create a one-week discrepancy in March and October/November.
