Sharepoint Calendar Time & Weekday Validation Issues

Good Morning

I'm trying to setup validation settings for a SharePoint calendar that only allows users to book between 7:30am - 2:30pm and only on weekdays.  The formulas by themselves seem to work great, but I do not know how to put them together so they act as one formula.  Any help would really be appreciated.

Thanks

Time Formula:

=AND(TIME(HOUR([Start Time]),MINUTE([Start Time]),SECOND([Start Time]))>=TIME(7,30,0),TIME(HOUR([End Time]),MINUTE([End Time]),SECOND([End Time]))<=TIME(14,30,0))

Weekday Formula:

=AND(WEEKDAY([Start Time])<>1,WEEKDAY([Start Time])<>7)
