About Paris Time (Central European Time)
Paris operates on Central European Time (CET), shared with most of Western and Central Europe including Berlin, Madrid, Rome, Amsterdam, and Brussels. This makes the CET zone one of the most economically significant time zones in the world, covering the European Union's largest economies.
During standard time (late October to late March), Paris is at UTC+1. In summer, France switches to Central European Summer Time (CEST) at UTC+2. The transition follows EU rules: clocks spring forward on the last Sunday of March at 2:00 AM and fall back on the last Sunday of October at 3:00 AM.
Paris is a major global business centre, home to the Euronext Paris stock exchange (formerly the Paris Bourse), which opens at 9:00 AM and closes at 5:30 PM CET. The city also hosts the headquarters of UNESCO, OECD, and numerous multinational corporations.
For transatlantic business, Paris has a 6-hour lead over New York (EST) and a 9-hour lead over Los Angeles (PST). The overlap with New York business hours typically runs from 3:00 PM to 5:30 PM CET. With Asian partners, Paris morning hours align with late afternoon in Tokyo and Singapore.
The European Union has debated abolishing seasonal clock changes since 2019. If adopted, France would likely stay on permanent CEST (UTC+2), though no final decision has been implemented as of 2026. Until then, remember to account for the twice-yearly time shift when scheduling.
