Doha is 7 hours ahead of Philadelphia
Best overlap: 8:00 AM to 11:00 AM in Philadelphia is 3:00 PM to 6:00 PM in Doha.
Book within 8:00 AM to 11:00 AM Philadelphia time (3:00 PM to 6:00 PM in Doha) and both teams will be at work. Doha is 7 hours ahead of Philadelphia, so you've got a workable 3-hour overlap — ideal for a standing meeting around 8:00 AM in Philadelphia (3:00 PM in Doha). Daylight saving complicates things slightly: Philadelphia observes it, Doha doesn't, so the difference flexes by an hour part of the year.
