on time vs. in time

I want to know the correct form
You should come to school on time or in time?

Hi. Please end all sentences with the proper punctuation.

“On time” means “punctually.” “In time” means “eventually.”

I am fairly certain you are searching for the former.

Please make sure you arrive on time.
Cheer up, kid! Things will get better in time.


Hi Itz,

Can you please do us a favor and use a more descriptive title for your question next time? ‘Clear my doubt’ is not very helpful. Also, you might want to read this thread which I found by using the search function: In/on time[YSaerTTEW443543]

in time (for something/to do something)
not late; with enough time to be able to do something
:black_small_square: Will we be in time for the six o’clock train?
:black_small_square: The ambulance got there just in time (= to save somebody’s life).

on time
at or before the correct moment : at a time that is not late
:black_small_square: Try to be there on time.
:black_small_square: I paid all of my bills on time [=when they were due] this month.
:black_small_square: Please hand in your homework on time.
:black_small_square: We arrived right on time. [=exactly at the right time]

That’s a good point, Tofu. Thanks.

On time = at the planned time; neither late nor early:

Peter wants the meeting to start exactly on time.
In time = with enough time to spare; before the last moment:

He would have died if they hadn’t got him to the hospital in time." p. 450
