Difference Between On time and In time

In our day to day life, we make plans and schedule our activities, for which we often use of the words on time and in time. These are often used interchangeably, but they are not one and the same thing, in the sense that ‘on time‘ is used to mean at the specific time, while ‘in time‘ means early enough. Let’s take a look at these examples to understand them better:

• Why are you never on time? If you’ve reached here in time, then we had not missed the beginning of the movie.
• She likes to get up in time, to do all the routine activities and reach the office on time.
• I hope you get home in time, to watch your favourite show on time.
• What will you do, if you are not there in time, and the event started on time?

In these two examples, we’ve used the word on time to refer something that happens on a particular time, whereas the word in time is used to mean without being late or not later than the desired time.

Definition of On time

The term on-time is an adjective, which reflects timeliness, i.e. happening of an event according to the schedule or plan. It is used to talk about something which occurs, arrives or is performed, on the set or expected time and is not late. For example:

• If I leave now, I will reach there on time.
• Joe asked if the flight was on time?
• I don’t think Kate will complete the project on time.
• From tomorrow, all the employees have to be on time, or else their salaries will be deducted.
• The interview started on time.
• The seminar is fixed at 4 pm; Please reach on time.

Definition of In time

The term ‘in-time’ means at the edge of a particular time. It is used when something happens just at the end moment. The term often points out that you do not have sufficient time between now and when something is expected to take place, to not to be late. For example:

• She arrived just in time for the class.
• I want to reach home in time, to meet the guests.
• Will you complete the homework in time?
• The construction of the building is completed in time for the inauguration.
• Disha said to her husband, “If you get home in time, we will go for a dinner.”
• We got to the stadium just in time, to watch the cricket match.

• I will reach the restaurant at 12 pm; please be on time.
• Don’t worry we’ll reach the hospital on time.
• The flight was late today. However, it’s usually on time.

In-time

• The trimmer didn’t seem to be delivered in time, with the other stuff ordered online.
• We are sure that Joseph will finish the work in time.
• Kate almost forgot to deliver the parcel. Luckily, she remembered in time.

How to remember the difference

With the above discussion, it may be clear to you that we use the word ‘on time’ for something that takes place on the scheduled time, but we use ‘in time’ for something that takes place in the final time, i.e. doing something before the time is over or something becomes unavailable.
