Hi guys, I am trying to calculate downtime between two dates.

Taking the first as example: Outage started on 1st and ended on 19th. Now Between 1st and 19th, I only want to calculate outage from 10:00 to 20:00 (support hours).

Taking the second row as example - clearly on sunday (5th Oct), there is the outage of 9 mins however it calculates 10 hours (total support hours)..??

Using the following formula i am able to calculate the outage from Monday to saturday (Outage hrs)
=IF(C2="",0,(NETWORKDAYS.INTL(B2,C2,11)-1)*(F2-E2)+IF(NETWORKDAYS.INTL(C2,C2,11),MEDIAN(MOD(C2,1),E2,F2),F2)-MEDIAN(NETWORKDAYS.INTL(B2,B2,11)*MOD(B2,1),E2,F2))

but unable to calculate the downtime of sundays (outage hours (sunday)), for which I am using the following formula:

=IFERROR(G2*SUMPRODUCT(--(WEEKDAY(ROW(INDIRECT(INT(B2)&":"&INT(C2))))=1)),0)

B2 - Start date
C2 - End Date
D2 - Total Duration
E2 - Service start time
F2 - Service end time
G2 - serice hours sunday
H2 - Service support type
J2 - outage hours
K2 - Outage hours (sun)


Thanks for your help in advance!!
