Departure time refers to the specific moment when a vehicle, such as a train, bus, or airplane, leaves a station or terminal. It is important for passengers to know this time so they can arrive on time and avoid missing their ride. Departure times are usually listed on tickets, schedules, or digital displays at transportation hubs. Knowing the departure time helps travelers plan their journey effectively. For example, if a flight is scheduled to depart at 3:00 PM, passengers should aim to arrive at the airport well in advance to check in and go through security. This ensures a smooth travel experience.
