Budapest is 3.5 hours behind Colombo
Best overlap: 11:30 AM to 6:30 PM in Colombo is 8:00 AM to 3:00 PM in Budapest.
Plan around 11:30 AM to 6:30 PM in Colombo, which is 8:00 AM to 3:00 PM in Budapest, to catch everyone during office hours. Budapest is 3.5 hours behind Colombo, but you'd hardly notice — 7 hours of shared hours makes this feel like working in neighbouring time zones. Daylight saving complicates things slightly: Budapest observes it, Colombo doesn't, so the difference flexes by an hour part of the year.
