Hi @Andy ,

Try this formula:

IF(ISERROR(DATEDIF([Start Date],[End Date],"d")),"",(DATEDIF([Start Date],[End Date],"d"))+1-INT(DATEDIF([Start Date],[End Date],"d")/7)*2-IF((WEEKDAY([End Date])-WEEKDAY([Start Date]))<0,2,0)-IF(OR(AND(WEEKDAY([End Date])=7,WEEKDAY([Start Date])=7),AND(WEEKDAY([End Date])=1,WEEKDAY([Start Date])=1)),1,0)-IF(AND(WEEKDAY([Start Date])=1,(WEEKDAY([End Date])-WEEKDAY([Start Date]))>0),1,0)-IF(AND(NOT(WEEKDAY([Start Date])=7),WEEKDAY([End Date])=7),1,0))
