Best overlap: 11:30 AM to 6:30 PM in Colombo is 8:00 AM to 3:00 PM in Amsterdam.
Plan around 11:30 AM to 6:30 PM in Colombo, which is 8:00 AM to 3:00 PM in Amsterdam, to catch everyone during office hours. This is one of the easier pairings: 7 hours of shared time means flexible, low-stress scheduling. Don't be caught out by clock changes — Amsterdam observes daylight saving and Colombo doesn't, so the offset varies by an hour through the year.
