Islamabad is 3 hours ahead of Tel Aviv
Best overlap: 8:00 AM to 3:00 PM in Tel Aviv is 11:00 AM to 6:00 PM in Islamabad.
8:00 AM to 3:00 PM in Tel Aviv is when Islamabad is also working, at 11:00 AM to 6:00 PM their time. The 3-hour gap barely gets in the way — you've got 7 hours of overlap, so pick whatever time fits the agenda. Heads up: because Tel Aviv changes its clocks and Islamabad doesn't, the difference moves by an hour twice a year. Confirm the overlap around the DST switch.
