Frequently Asked Questions — Time Zone Converter

How does the time zone converter work?

Select your source timezone and enter the date/time, then choose your target timezone. The tool instantly calculates and displays the converted time along with the time difference. You can swap the source and target with one click. The big result display shows both times side by side.

What time zones are supported?

The converter supports 22 major global time zones including UTC, all US zones (EST/EDT, CST/CDT, MST/MDT, PST/PDT, AKST/AKDT, HST), European zones (GMT/BST, CET/CEST, MSK), Middle East (GST), South Asia (PKT, IST, BST), Southeast Asia (ICT, SGT), East Asia (JST, KST, CST), and Oceania (AEST/AEDT, NZST/NZDT). Quick-select buttons for 9 major cities make switching fast.

Does the time zone converter account for daylight saving?

Yes! The converter uses the browser's built-in Intl.DateTimeFormat API, which automatically accounts for Daylight Saving Time (DST) transitions based on the selected timezone and date. For example, New York automatically switches between EST (UTC-5) and EDT (UTC-4).
