Portland is typically 9 hours behind Paris. When it's 5:00 PM in Paris, it's 8:00 AM the same day in Portland. Both cities observe daylight saving time, but the transition dates differ slightly.
During most of the year, the difference is 9 hours. During the brief periods when Europe and the US change clocks on different weekends (usually in March and November), the difference can temporarily be 8 or 10 hours.
Optimal meeting window: 8:00 AM - 10:00 AM Portland time (5:00 PM - 7:00 PM Paris). Morning Portland catches late afternoon Paris.
Portland has a sister city relationship with several French cities and shares cultural similarities with Paris in terms of food culture, cycling, and urban planning.
