Bogotá is 1 hour behind Philadelphia
Best overlap: 9:00 AM to 6:00 PM in Philadelphia is 8:00 AM to 5:00 PM in Bogotá.
Target 9:00 AM to 6:00 PM in Philadelphia, which lands at 8:00 AM to 5:00 PM for the Bogotá side. That's a roomy 9 hours of common time each day, so finding a slot that suits everyone is rarely a problem. Daylight saving complicates things slightly: Philadelphia observes it, Bogotá doesn't, so the difference flexes by an hour part of the year.
