Workday

Can you help me? How can I put in the intermediate gaps H7, H6, H9, H8.
H5 - H4 - no work is done, and the time to be postponed to 00:30 minutes
H7 - H6 - no work is done, and the time to be postponed to 00:15 minutes
H9 - H8 - - no work is done, and the time to be postponed to 00:15 minutes

There is a formula right now (C2)= =WORKDAY(B2;MAX(ROUNDUP((E2-IF((COUNTIF($J$4:$J$91;INT(B2))=0)*(WEEKDAY(B2;2)<=5);IF(MOD(B2;1)>$H$3;0;IF(MOD(B2;1)>=$H$5;(H3-MOD(B2;1))*24;($H$3-MAX(MOD(B2;1);$H$2)-($H$5-MAX(MOD(B2;1);$H$4)))*24));0))/(($H$3-$H$2-($H$5-$H$4))*24);0);0);$J$4:$J$91)+$H$2+(IFERROR(CEILING(MOD((E2-IF((COUNTIF($J$4:$J$91;INT(B2))=0)*(WEEKDAY(B2;2)<=5);IF(MOD(B2;1)>$H$3;0;IF(MOD(B2;1)>=$H$5;($H$3-MOD(B2;1))*24;($H$3-MAX(MOD(B2;1);$H$2)-($H$5-MAX(MOD(B2;1);$H$4)))*24));0))/(($H$3-$H$2-($H$5-$H$4))*24);1)-0,00000001;0,00000001);1)*($H$3-$H$2-($H$5-$H$4))*24+(IFERROR(CEILING(MOD((E2-IF((COUNTIF($J$4:$J$91;INT(B2))=0)*(WEEKDAY(B2;2)<=5);IF(MOD(B2;1)>H3;0;IF(MOD(B2;1)>=$H$5;($H$3-MOD(B2;1))*24;($H$3-MAX(MOD(B2;1);$H$2)-($H$5-MAX(MOD(B2;1);$H$4)))*24));0))/(($H$3-$H$2-($H$5-$H$4))*24);1)-0,00000001;0,00000001);1)*($H$3-$H$2-($H$5-$H$4))*24>($H$4-$H$2)*24)*($H$5-$H$4)*24)/24

and

C3 = =WORKDAY(B3;MAX(ROUNDUP((E3-IF((COUNTIF($J$4:$J$91;INT(B3))=0)*(WEEKDAY(B3;2)<=5);IF(MOD(B3;1)>$H$3;0;IF(MOD(B3;1)>=$H$5;(H4-MOD(B3;1))*24;($H$3-MAX(MOD(B3;1);$H$2)-($H$5-MAX(MOD(B3;1);$H$4)))*24));0))/(($H$3-$H$2-($H$5-$H$4))*24);0);0);$J$4:$J$91)+$H$2+(IFERROR(CEILING(MOD((E3-IF((COUNTIF($J$4:$J$91;INT(B3))=0)*(WEEKDAY(B3;2)<=5);IF(MOD(B3;1)>$H$3;0;IF(MOD(B3;1)>=$H$5;($H$3-MOD(B3;1))*24;($H$3-MAX(MOD(B3;1);$H$2)-($H$5-MAX(MOD(B3;1);$H$4)))*24));0))/(($H$3-$H$2-($H$5-$H$4))*24);1)-0,00000001;0,00000001);1)*($H$3-$H$2-($H$5-$H$4))*24+(IFERROR(CEILING(MOD((E3-IF((COUNTIF($J$4:$J$91;INT(B3))=0)*(WEEKDAY(B3;2)<=5);IF(MOD(B3;1)>H4;0;IF(MOD(B3;1)>=$H$5;($H$3-MOD(B3;1))*24;($H$3-MAX(MOD(B3;1);$H$2)-($H$5-MAX(MOD(B3;1);$H$4)))*24));0))/(($H$3-$H$2-($H$5-$H$4))*24);1)-0,00000001;0,00000001);1)*($H$3-$H$2-($H$5-$H$4))*24>($H$4-$H$2)*24)*($H$5-$H$4)*24)/24

The result is not right. Because the correct result is in cell D. here is the formula (I-Pause start time and I pause start end;II-Pause start time and II pause start end)
