EST to CET
Paris is 6 hours ahead of New York, and does not change across the year.
EST and CET across the year
Both zones change their clocks on the same dates, so the gap between them never moves — Paris is 6 hours ahead of New York all year. Note that this is a fixed difference, not a fixed offset: both cities still shift by an hour twice a year, so a time expressed in UTC will change even though the gap between these two does not.
EST: Eastern Time is EDT (UTC−4) in summer and EST (UTC−5) in winter. The figures here follow the current rule rather than assuming winter.
CET: CET (UTC+1) becomes CEST (UTC+2) in summer. It covers most of western and central Europe — Paris, Berlin, Madrid, Rome and Amsterdam all share it.

Scheduling between New York and Paris
The workable window is 9:00 am to 12:00 pm in New York — 3:00 pm to 6:00 pm in Paris. That is 3 hours out of a nine-hour working day, and everything outside it costs somebody their morning or their evening.
Three hours or fewer is a tight window, and it fills up fast once both sides have their own internal meetings in it. If this pair is a regular working relationship, it is worth treating that window as protected time — the scarcest shared resource the two teams have — rather than letting it be consumed by whatever gets booked first.
The two edges behave differently. Booking at 9:00 am New York time means Paris is late in its afternoon and may be winding down; booking at 11:00 am means New York is mid-afternoon while Paris is closer to the end of the day. Where the decision matters, give the later-in-the-day side the earlier slot.
If you are the one in New York
Paris is ahead of you, which means their day is already ending as yours gets going. By the time you are at your desk at 9:00 am, it is 3:00 pm there — so anything you send in your morning arrives in their afternoon, with time to act on it. The practical consequence is that your late afternoon is dead time for anything needing a reply from Paris: they are asleep, and you will not hear back until your next morning.
So the discipline that pays off is front-loading. Anything Paris needs from you should go out early in your day while they are still working; anything you need from them should be asked for before you leave, so it is waiting when you return. Treat their evening as the deadline, not yours.
