How do time zones work?

Earth is divided into 24 zones, each roughly 1 hour apart from UTC. Local time = UTC + offset (e.g., EST = UTC-5).

Coordinated Universal Time—the primary time standard. It doesn't observe DST. GMT is essentially the same as UTC.

How does DST affect conversion?

Some zones shift 1 hour seasonally. Our calculator adjusts automatically based on the selected date and time.
