How this calculator works
The result depends on the numbers you enter and the assumptions shown below.

Time zones are offsets from UTC. Converting between zones: calculate the UTC time, then apply the target offset. Daylight saving time is not accounted for in this fixed-offset calculator.

Review the inputs carefully and treat the output as an estimate. For decisions involving money, taxes, health, law, or security, compare the result with trusted professional guidance when needed.

Frequently asked questions

What is UTC?

UTC (Coordinated Universal Time) is the primary time standard. All time zones are defined as UTC+/−hours. New York is UTC−5 (EST) or UTC−4 (EDT during daylight saving).
