Time difference between Paris and New York

The gap is not the same all year

Every converter gives one number for this pair. That number is right for most of the year and wrong for part of it, because Paris goes forward on the last Sunday in March and back on the last Sunday in October and New York goes forward on the second Sunday in March and back on the first Sunday in November.

Both change their clocks and both are in the northern hemisphere, but not on the same weekend — Paris goes forward on the last Sunday in March and New York on the second Sunday in March. For the days in between, the gap is neither party's expected figure, and a standing meeting silently moves by an hour. That mismatch is a common cause of a missed international call.

About Paris and New York

France is on Central European Time and geographically should not be — Paris sits almost on the Greenwich meridian. It has been an hour ahead of the sun since the occupation in 1940 and never went back, which is why sunset in Paris is so much later than in London for the same latitude.

New York is UTC−5 in winter and UTC−4 from March to November, and it changes clocks on different weekends from Europe — a fortnight in March and a week in autumn when the transatlantic gap is an hour off what everyone expects.

What 6 hours actually costs you

The window is 2 hours wide and that is all there is. 3:00 PM–5:00 PM in Paris is 9:00 AM–11:00 AM in New York, and anything outside it puts somebody at their desk when they are not meant to be. A pair this tight is worth putting in a calendar rather than agreeing each time.

When they can both be at their desks

Nine-to-five in both cities overlaps for 2 hours — 3:00 PM to 5:00 PM in Paris, the same moment as 9:00 AM to 11:00 AM in New York.

How far apart Paris and New York are

The shortest path over the Earth's surface between the two is 5,837 km (3,627 miles). Flown along that line, an airliner at cruising speed takes roughly 7 hours 30 minutes in the air — actual routings add to it, and whether a nonstop service exists depends on the airlines rather than the distance.

Over that distance you cross 6 hours of clock, which is where jet lag comes from: the body shifts by about an hour a day, so 6 hours takes most people 6 days or so to absorb. Flying west to New York is the easier direction — you gain the hours, and staying up later comes more naturally than going to bed early.
