- Greenwich Mean Time (GMT): GMT is five hours ahead of ET (or four hours ahead of EDT during DST).
Plan Accordingly: Use the calculated time differences to schedule meetings, make travel plans, and communicate effectively with people in different locations. Always double-check the time to ensure accuracy.
