Frequently Asked Questions

Does this handle daylight saving time?

Yes. The converter uses your browser's built-in timezone database (IANA Time Zone Database) which automatically handles all DST transitions. Conversions are accurate for any date, including historical and future dates.

What do the green highlights mean?

In the hour-by-hour comparison, green numbers indicate business hours (9:00 AM - 5:00 PM) in the destination timezone. This makes it easy to find suitable times for calls or meetings across time zones.

What is UTC?

UTC (Coordinated Universal Time) is the world's primary time standard. All time zones are defined as offsets from UTC. For example, EST is UTC-5, JST is UTC+9. UTC itself does not observe daylight saving time.
