Paris — CET/CEST at the heart of Europe
Paris runs on CET (winter) or CEST (summer). Same offset as Berlin, Amsterdam, Madrid, Rome, Warsaw. French business hours 9 AM - 6 PM with a 1-1.5 h lunch (12:30 - 2 PM). French labor law caps the standard week at 35 h — one of the shortest in the OECD — but corporate life in Paris tends to exceed that comfortably. Euronext Paris trading runs 9 AM - 5:30 PM CET.
