Hi @Johnny Harrang ,
Welcome to Q&A forum!
According to your description, the following formula is just a reference, you can change it according to your needs. In my test case, the working hours are 8:00 am-18:00 pm from Monday to Friday.
=IF(AND(WEEKDAY(E2)>=6,WEEKDAY(F2>=6)),"100%",IF(DAYS(F2,E2)=0,IF(AND(HOUR(E2>=8),HOUR(F2)<=18),"100%",ROUND((MOD(F2,1)-"18:00")/(F2-E2)*100%,1)),IF(AND(HOUR(E2)>=18,HOUR(F2)<=8),"100%",ROUND(("6:00"+MOD(F2,1))/(F2-E2)*100%,1))))
----------
Update：
Please check the following formulars:
- E2:
IF(I2<=5,IF(AND(("15:30"-C2)>=0,("15:30"-D2)>=0),D2-C2,IF(AND(("15:30"-C2)>=0,("15:30"-D2)<0),"15:30"-C2,"")),"")
- F2:
IF(I2<=5,IF(AND(("15:30"-C2)>=0,("15:30"-D2)>=0),"",IF(AND(("15:30"-C2)>=0,("21:00"-D2)<0),"21:00"-"15:30",IF(AND(("15:30"-C2)>=0,("21:00"-D2)>=0),D2-"15:30",IF(AND(("15:30"-C2)<0,("21:00"-C2)>=0,("21:00"-D2)>=0),D2-C2,IF(AND(("15:30"-C2)<0,("21:00"-C2)>=0,("21:00"-D2)<0),"21:00"-C2,""))))),"")
- G2:
IF(I2>5,D2-C2,IF(AND(("21:00"-C2)<0,("21:00"-D2)<0),D2-C2,IF(AND(("21:00"-C2)>=0,("21:00"-D2)<0),D2-"21:00","")))
Hope the information is helpful to you.
