How to display at specific times, campaign

Hi,

I have a problem planning a campaign.
I need to plan a campaign from today to 31.03.2025.
The campaign is to be displayed every 2.5 minutes while the screen is on. The screen is on from 09:00 to 19:00.
Should I calculate the total number of views myself?
Is it possible to set the time interval?
Does the program take into account the screen’s on time or 24 hours?
Can someone demonstrate how to set this up?
Should I choose plays or impressions?
I have one layout displayed non-stop while the screen is on.

Thank you
