Why should “Can you come in tomorrow at 1:00 pm?” instead of “Can you come on tomorrow at 1:00 pm?”?
Is it means that she comes at the office before 1.00 pm?

Many thanks for the incoming answers.

Both ‘on’ and ‘at’ are wrong. She comes to the office and then she comes into the office.

I know now that ‘come in’ is a phrasal verb. It means to arrive. I was trapped the word ‘tomorrow’ (like on Monday, Tomorrow, etc). Now, I understand.

Many thanks Mr. Micawber for you corrections. It really helps me.

the same happened to me. I was trapped by the word “tomorrow”
