UTC-offset time conversion
Convert a date and time between two known UTC offsets.
How this works
Destination local time = source local time − source UTC offset + destination UTC offset.
Example
Using the example inputs, destination time is 06:00.
- Source date
- 2026-10-22
- Source time
- 14:00
- Source UTC offset
- -7 hours
- Destination UTC offset
- 9 hours
- Destination time
- 06:00
Enter the correct offset for the date, including any daylight-saving change.
Scope and assumptions
Fixed offsets only, not automatic city time zones or daylight-saving rules.
