We are often confused when using a preposition before a day of the week, for example, Monday. In this article, we will learn which one is correct, On Monday or At Monday.
On Monday or At Monday – Which one is Correct?
“On Monday” is correct usage while “At Monday” is incorrect usage in a sentence. A day of the week takes the “On” preposition instead of “At“.
- See you on Monday. (Correct)
- See you at Monday. (Wrong)
- I am available on Monday. (Correct)
- I am available at Monday. (Wrong)
Usage of “On”
Preposition: I’m going on vacation next week.
Adverb: The car is going on the highway.
Adjective: I’m feeling on edge today because of the uncertainty in my life.
