What does this tool do?
Time zones are defined by their offset from UTC, and crossing several zones can move the clock into the next or previous day. This converter uses fixed offsets, so it does not apply daylight saving rules.
The Formula
Target time = source time + (target offset − source offset)Frequently Asked Questions
Why did the date change?
When the converted time passes midnight, the clock rolls into the next or previous day. The day-change row tells you which.
Does this handle daylight saving time?
No. It uses the fixed offsets you select. For a specific date, use the offset that region observes on that date, including daylight saving if applicable.
