Frequently Asked Questions

How many timezones does the converter support?

The converter supports 18 popular timezones covering all major regions worldwide, including UTC, US Eastern, US Pacific, Europe London, Asia Shanghai, Asia Tokyo, and more. Each timezone displays its UTC offset for clarity.

How do I swap the source and target timezones?

Click the swap button between the two timezone selectors to instantly swap the source and target timezones. The current input time is also converted to the new target timezone automatically.

Does it account for daylight saving time?

Yes. The converter uses the browser's built-in Intl.DateTimeFormat API, which automatically handles daylight saving time transitions for each timezone. Results reflect the correct time offset including DST adjustments.

What format should I enter the date and time?

Use the date and time picker to select values, or type directly in ISO format (YYYY-MM-DD HH:mm). The converter validates your input and shows an error message if the format is incorrect.

Can I copy the conversion result?

Yes. Click the copy button next to the result to copy the converted time and date information to your clipboard. The copied text includes both the source and target timezone details.
