How it is calculated
Dammam is fixed at UTC+3. Subtract 3 hours to get UTC, then add the Houston offset on that date (UTC-6 in winter, UTC-5 in summer) from the IANA time-zone database, zone America/Chicago.
Example
Inputs: Date in Dammam = 2026-07-15, Time in Dammam = 09:00. Result: Time in Houston: 01:00 Wednesday; Date in Houston: Wednesday, July 15, 2026 (2026-07-15); Time difference: -8 hours.
Limits and caveats
- DST dates and zone rules come from the time-zone database on your device or browser, so a recent rule change it has not received can shift the result.
- Houston follows US Central Time.
