Common questions

How many hours ahead is Busan of New York?

What is the best time to call between New York and Busan?

There is no hour inside working hours in both cities. 17:00–18:00 your time (06:00 there) is the cheapest compromise, and one side is taking a shoulder hour.

Do New York and Busan change clocks on the same date?

Only one of them does, so the gap between them changes twice a year even though neither city moved relative to the sun.
