He is available for the interview in/on the below mentioned schedule

I am replying to my client about the availability of a person for the interview.

Which one is correct to use. "in" or "on"?

He is available for the interview in/on the schedule mentioned below.


Solution 1:

"He is available for the interview [at these times], on these dates: " will be less ambiguous.

"He is available for the interview between these dates". if you are not bothered about a specific date or time...
