How to calculate delivery date taking account of tea break, lunch break, weekends and holidays?

[cutiegal886]

Hi All,

I'm trying to calculate a production delivery date that account for tea&lunch break, weekends and holidays. I found a useful equation, as shown below, but it doesn't take into account of the tea&lunch breaks in between. Could anyone help me with this?

	A	B	C	D	E	F	G
1	Start	Hours	End		Begin	End	Holiday
2	2017-7-15 08:30	5			8:00	5:00	2017-7-16

=WORKDAY(A2,INT(B2/8)+IF(TIME(HOUR(A2),MINUTE(A2),SECOND(A2))+TIME(MOD(B2,8),MOD(MOD(B2,8),1)*60,0)>$F$2,1,0),$G$2:$G$2)+IF(TIME(HOUR(A2),MINUTE(A2),SECOND(A2))+TIME(MOD(B2,8),MOD(MOD(B2,8),1)*60,0)>$F$2,$E$2
+TIME(HOUR(A2),MINUTE(A2),SECOND(A2))+TIME(MOD(B2,8),MOD(MOD(B2,8),1)*60,0)-$F$2,TIME(HOUR(A2),MINUTE(A2),SECOND(A2))+TIME(MOD(B2,8),MOD(MOD(B2,8),1)*60,0))

My tea & lunch breaks are as follows:
10:00~10:15 Morning Tea
12:00~13:00 Lunch
15:00~15:15 Afternoon Tea

Thanks James for your input! I'm not exactly sure how to apply it to my information though.
