Live time conversion and hour-by-hour comparison
This page shows the live time conversion between New York and Paris. The hour-by-hour chart above makes it easy to find overlapping business hours for meetings or calls. Green highlights indicate standard business hours (9 AM – 5 PM) in each city.
New York and Paris are 6 hours apart during winter and typically 6 hours during most of the year. However, during the 2-3 week spring window when the US has already changed clocks but France hasn't, the gap shrinks to 5 hours. The same happens briefly in fall. The standard 6-hour gap means morning Paris overlaps with early morning New York — challenging but workable for the critical transatlantic business corridor.
The New York-Paris axis drives the global fashion industry. Fashion weeks in both cities are scheduled back-to-back on the industry calendar. Buyers, designers, and media fly between the two cities regularly. Major luxury conglomerates (LVMH, Kering) headquartered in Paris manage significant US retail operations coordinated with New York. The 6-hour gap means Paris fashion executives often take late-afternoon calls with New York colleagues.
The Euronext Paris and NYSE have a meaningful overlap window. Euronext opens at 9 AM CET (3 AM ET) and closes at 5:30 PM CET (11:30 AM ET). NYSE opens at 9:30 AM ET (3:30 PM CET). The overlap from 3:30 PM to 5:30 PM Paris time (9:30 AM to 11:30 AM ET) is when transatlantic equity coordination peaks. This 2-hour window drives significant trading volume.
The sweet spot for New York-Paris calls is 9-11 AM ET (3-5 PM CET). Both sides are well within business hours. Avoid scheduling before 8 AM ET (2 PM CET is fine but leaves little Paris afternoon). The classic French lunch (typically 12:30-2 PM CET) means 6:30-8 AM ET calls may not reach your Paris contact. Build in cultural awareness: French business culture values the lunch break more than American culture does.
