Many people confuse these two expressions. And while they are similar, there is a very important difference.
- ON time – This referrs to when you have an appointment or scheduled time to be somewhere or do something.
The meeting starts at 2 pm. I have to be on time. (If I’m late something bad will happen.)
The flight left on time. (It took off at the scheduled time)
TIP: I tell my students to associate the O of ON TIME with the face of a clock to remember that on time has a set time!
- IN time – This refers to being early ehough to be able to do something or experience something.
Even though I arrived late for the meeting I was still in time because it hadn’t started.*
I forgot to set my alarm but luckily I woke up in time to have breakfast.
NOTE: It is possible to be late (not on time) for an appointment and still be in time to participate in the experience.
