DAYS vs. NETWORKDAYS (Updating an existing formula)

DAYS vs. NETWORKDAYS

How would I adjust these formula's to use actual days and NOT NETWORKDAYS:
=IF( OR( BN3236 ="", P3236 = "", NETWORKDAYS(BN3236,O3236)<0 ),-1, NETWORKDAYS(BN3236,O3236))
=IF( OR( BO3236 ="", BA3236 = "", NETWORKDAYS(BO3236,BA3236)<0 ),-1, NETWORKDAYS(BO3236,BA3236))

Thank you!
