# Get minute difference between working days and hours

##### Board Regular
Hi Everyone,

Would like to seek for your help on how can I get minute difference between two dates considering working days and working hours

Working days - Monday to Friday
Working Hours - 8AM - 6PM

Sample Scenario

 Start Date Finished Date Desired Result in minutes 2/14/2018 6:30:00 PM 2/14/2018 8:45:00 AM 45 mins 2/15/2018 6:00:00 PM 2/18/2018 8:30:00 AM 30 mins

Why does 9 mean SUM in SUBTOTAL?
It is because Sum is the 9th alphabetically in Average, Count, CountA, Max, Min, Product, StDev.S, StDev.P, Sum, VAR.S, VAR.P.

Hi Elli,
You could try this formula
Code:
``[COLOR=#444444][FONT=Calibri]=((((B2-A2)-(DAYS(B2,A2)+1-NETWORKDAYS.INTL(A2,B2,1)))*24)-10)*60[/FONT][/COLOR]``
Where A2 has the start datetime and B2 has the end datetime

Hi. How could I exclude those time (minutes) from 6:00pm - 8am?

That is what the formula does, it excludes time from 6 pm to 8 am

Hi I tried to simulate based on my given example above but I got -1185 and 270 and not the desired result in my query. Thanks.

oh yes you are right, your not working hours are 14 not 10 in your case, so the formula is
Code:
``=((((B2-A2)-(DAYS(B2,A2)+1-NETWORKDAYS.INTL(A2,B2,1)))*24)-14)*60``
Btw your first row data start date time is greater then finished date time you shod correct this
Cheers
