9am in Tokyo is 1am in Lisbon

When it’s 9am in Lisbon, it’s 6pm in Tokyo. Tokyo is 9 hours ahead Lisbon. Lisbon observes daylight saving time but Tokyo does not, so the gap shifts by one hour during clock changes. The best time to schedule calls between the two cities is outside standard hours for at least one city, so flexibility is key. Remote teams spanning Lisbon and Tokyo typically designate a fixed overlap window for synchronous meetings, with async handoffs covering the rest. In practice, teams in Lisbon tend to take early-morning calls to reach Tokyo during standard afternoon hours, while Tokyo counterparts can schedule near end of day. Asynchronous handoffs using shared documents or recorded video updates help bridge the hours when schedules do not overlap.
