How does a time zone converter work?

It applies the UTC offset difference between two zones to convert a given time.

Why do conversions sometimes seem off by an hour?

Daylight saving time can shift a zone's offset seasonally.

What Is a UTC Offset?

Every time zone in the world is defined by its offset from Coordinated Universal Time (UTC) — for example, New York is typically UTC-5, and Dubai is UTC+4. Converting between time zones means adding or subtracting the difference in offsets.

Formula

Converted Time = Original Time + (To Offset - From Offset)
