Kuala Lumpur is 6 hours ahead of Oslo
Best overlap: 8:00 AM to 12:00 PM in Oslo is 2:00 PM to 6:00 PM in Kuala Lumpur.
Plan around 8:00 AM to 12:00 PM in Oslo, which is 2:00 PM to 6:00 PM in Kuala Lumpur, to catch everyone during office hours. A 4-hour overlap gives you a workable daily window; aim for earlier in it to avoid clipping the end of someone's day. Daylight saving complicates things slightly: Oslo observes it, Kuala Lumpur doesn't, so the difference flexes by an hour part of the year.
