How many hours is Copenhagen ahead of New York?

Copenhagen is normally 6 hours ahead of New York. This applies when both cities are on standard time (EST/CET, November to mid-March) or when both are on daylight saving time (EDT/CEST, late March to early November). During the brief transition weeks in spring and autumn when clocks change on different dates, the offset can be 5 or 7 hours.

Does the offset change for daylight saving time?

The offset stays at 6 hours for most of the year because both New York and Copenhagen observe daylight saving time. However, they switch on different weekends. In spring, Europe switches a few weeks before the US, making Copenhagen temporarily 7 hours ahead. In autumn, Europe switches back first, briefly making Copenhagen only 5 hours ahead.

What time zones does each city use?

New York uses Eastern Time — EST (UTC-5) in winter and EDT (UTC-4) in summer. Copenhagen uses Central European Time — CET (UTC+1) in winter and CEST (UTC+2) in summer.

If it is 9 AM in New York, what time is it in Copenhagen?

During most of the year the offset is 6 hours, so 9 AM New York corresponds to 3 PM Copenhagen. Use the live clocks above to confirm the exact time right now, especially around DST transition dates.

How it works

Your browser's built-in Intl.DateTimeFormat API retrieves the current wall-clock time in each city's IANA time zone.
New York uses the "America/New_York" zone (UTC-5 in winter, UTC-4 in summer).
Copenhagen uses the "Europe/Copenhagen" zone (UTC+1 in winter, UTC+2 in summer).
The tool computes the hour offset by comparing the UTC offsets of both zones at the current moment.
Both clocks tick every second so the displayed times are always accurate.
The meeting planner converts any entered time from one city to the other using the live offset.
