Houston is typically 7 hours behind Amsterdam. When it's 6:00 PM in Amsterdam, it's 11:00 AM in Houston. Both cities observe daylight saving time, but they switch on slightly different schedules.
During most of the year, the difference is 7 hours. During the brief periods when US and EU DST schedules don't align (early March and late October/early November), the difference can vary by an hour.
Optimal meeting window: 8:00 AM - 11:00 AM Houston time (3:00 PM - 6:00 PM Amsterdam). Morning Houston catches afternoon Amsterdam before end of business.
Houston is the energy capital of the US, and Shell (headquartered in The Hague, near Amsterdam) has major operations there. The oil and gas industry drives significant business travel between these energy hubs.
