Determining headcount by summarizing Erlangs at daily, weekly, and month level.

I am putting together a staffing model to show the staffing needs at daily level (down to the 30 min interval) using Erlang. I am also trying to communicate what the staffing needs would then be at the weekly and monthly level.
The hours of operations span 17 hours a day 7 days a week, but Saturday and Sunday receive much lower volume, reflecting significantly less FTE.
I am trying to determine the ideal number of staff for the day (the average and max seem too low since the hours of operation are greater than 8 hours). Once I have the ideal Daily headcount number, how would I determine the ideal monthly headcount number, considering the weekends require much less staff.
Thank you for the help!
