Frequently Asked Questions

How do I convert time between time zones?

Select your source and target time zones from the dropdowns, then set the date and time you want to convert. The result updates instantly. Click "Now" to use the current time in your local zone.

Does this tool handle Daylight Saving Time (DST)?

Yes. The converter uses the browser's built-in Intl.DateTimeFormat API with IANA time zone identifiers. DST transitions are applied automatically based on the selected date, so the result is correct year-round.

What is UTC offset?

UTC (Coordinated Universal Time) is the world's primary time standard. A UTC offset shows how many hours and minutes a time zone is ahead (+) or behind (−) UTC. For example, New York uses UTC−5 in winter (EST) and UTC−4 in summer (EDT).

Why does the converted date sometimes differ by a day?

When the time difference crosses midnight, the resulting date in the target zone will be a day earlier or later than in the source zone. For example, 11 PM in New York on Monday is 4 AM in London on Tuesday.
