Islamabad is 4 hours ahead of Hamburg
Best overlap: 8:00 AM to 2:00 PM in Hamburg is 12:00 PM to 6:00 PM in Islamabad.
Both teams are at their desks between 8:00 AM to 2:00 PM in Hamburg and 12:00 PM to 6:00 PM in Islamabad. Plenty of room to work with: 6 hours of daily overlap means you can prioritise people's preferences over the clock. One seasonal catch: Hamburg springs forward and falls back, but Islamabad doesn't, so the gap changes by an hour for several months of the year.
