The phrases ‘on the schedule’ and ‘in the schedule’ can often cause confusion, but they have different meanings and usages in English.
‘On the schedule’ is used when referring to something that is planned to happen at a particular time. For instance, if you say, ‘The meeting is on the schedule for 10 AM,’ it indicates that the meeting is officially planned and included as a part of the timetable.
On the other hand, ‘in the schedule’ is typically used to refer to the actual list or document that outlines various events, tasks, or appointments. For example, if you say, ‘The meeting is in the schedule,’ it suggests that you can find the meeting listed within the schedule document, though it doesn’t specifically indicate the time aspect as clearly as ‘on the schedule’ does.
In summary, use ‘on the schedule’ when you want to highlight an event’s timing and planning status, and ‘in the schedule’ when you are talking about its actual listing in a schedule document.
