How many hours behind CET is EST?

Eastern Standard Time (EST, UTC−5) is 6 hours behind Central European Time (CET, UTC+1) during winter. In summer, when New York is on EDT (UTC−4) and Europe is on CEST (UTC+2), the gap remains 6 hours. During brief transition windows in March and October when the US and EU change clocks on different dates, the gap can be 5 or 7 hours.

What European cities use CET?

Central European Time (CET) is used by France, Germany, Italy, Spain, the Netherlands, Belgium, Austria, Switzerland, Poland, Sweden, Norway, Denmark, and many other continental European countries. In summer all these countries switch to CEST (UTC+2). Notable exceptions: the UK uses GMT/BST (1 hour behind CET), and Turkey uses TRT (UTC+3, permanently).

What is the best time for a call between New York and Paris or Berlin?

The workable window is 3–6 PM CET (9 AM–12 PM EST) in winter. This gives New York a morning slot and Europe a post-lunch afternoon. The 10 AM EST / 4 PM CET call is a popular choice that avoids both morning rush and late-afternoon Europe fatigue.
