ON time or IN time? – Learn FAST (2021)

Prepositions are difficult to learn in your second language, but they are important. More than one of my students has asked the question: “How do you use in and on for time?” They often ask how to use the common expressions IN time and ON time. Here is a quick answer:

ON time = not late
“The 10:35 train was ON time.” = It left at 10:35, it left the station at its planned time.

IN time = soon enough
“My train is late, I hope I am home IN time for dinner.” = Soon enough for dinner.

How do you use IN and ON for time?

On time

ON time = not late
If something happens ON time, it happens at the time which was planned.


“The 10:35 train was ON time.” = The train left at 10:35, it left the station at its planned time.

“Let’s meet at the restaurant at 6:30 tomorrow. Please be ON time because we have a reservation.” = Please don’t be late.
