How it is calculated
The Los Angeles time (IANA America/Los_Angeles) becomes UTC by subtracting its offset on that date, then the Riyadh offset (Asia/Riyadh) at the same instant is added: Riyadh time = Los Angeles time - Los Angeles UTC offset + Riyadh UTC offset.
Example
Inputs: Date in Los Angeles = 2026-07-15, Time in Los Angeles = 09:00. Result: Time in Riyadh: 19:00 Wednesday; Date in Riyadh: Wednesday, July 15, 2026 (2026-07-15); Riyadh vs Los Angeles: +10 hours.
Limits and caveats
- DST dates come from the device time-zone database, so a country rule change that your device has not received yet can shift the result.
- On a clock-change night in Los Angeles, a skipped or repeated local hour (such as 02:30 or 01:30) is read with one of the two offsets.
