Difference between two dates in excel 2013 - excel

I want to calculate the time difference between two dates with the following criteria:
1) excluding sundays and public holidays
2) TIMING: Mon to Fri = 7 AM to 7 PM &
Sat = 7 AM to 3 PM
I tried a many formulas and nothing works for me.
please any ideas??
Eg: Start Time: 3/6/2015 10:00 AM
End Time: 4/6/2015 12:00 PM
Then I should get the difference as 13 hrs (excluding time out of business hours)

If start and end "timestamps" will always be within working hours then you can use a formula like this:
=(SUM(NETWORKDAYS.INTL(A2,B2,{1,"1111101"},H$2:H$10)*{12,8})-IF(WEEKDAY(B2)=7,8,12))/24+MOD(B2,1)-MOD(A2,1)
Assuming start date/time in A2, end date/time in B2 and holiday list in H2:H10
Format result cell as [h]:mm and if start time is today (Monday) at 14:00 and end time is exactly a week later you will get the result 68:00 (5*12 hour days and 1*8 hour Saturday)

How to get time elapsed till 12:00 AM in same day and rest on next day

I am currently facing difficulty to calculate exact hours between In Time and Out time.
for instance :
Column A
Column B
Column C
Column D
1-1-2022
10:00 PM
1-2-2022
6:00 AM
1-2-2022
10:00 PM
1-3-2022
6:00 AM
Now, my problem is that I have to calculate the time from 10:00 PM till 12:00 AM = 2 Hours and rest to be calculated on the next day adding the previous days hours e.g. we have 6 hours from 12:00 AM till 6:00 AM for 1-2-2022 (Column C) and then 2 hours from 10:00 PM to 12:00 AM.
Looking forward your help.
You must add the date and times together, subtracting the In time from the Out time.
Slightly different method:
B2, D2 and E2 formatted as hh:mm
Then you could use mod() like so:
=MOD(D2-B2,1)

Add Time To A Date Only Inside Preset Hours

I am trying to do something as follows:
Date & Time: 27/09/2019 13:28
Working Day: Monday - Friday 8am - 5:30PM (08:00 -> 17:30) (NetworkDays)
Duration: 9.5hrs (09:30 hrs)
Outcome: 30/09/2019 13:28
Logic behind this is
Date & Time + Duration (Only inside the "Working Day") = Outcome
Working Days should only be from Monday - Friday 8am - 5:30pm and excludes weekends. I believe NetworkDays handles this?
If the Date & Time + Duration carries across weekend, then the time carries across to the following Monday.
Is there anything that can handle something like this?
Many thanks in advance
If A1 contains the Date/Time and A2 contains the Duration, then:
=WORKDAY(A1,INT((A1-INT(A1)-8/24+A2/24)/9.5*24))+8/24+MOD(A1-INT(A1)-8/24+A2/24,9.5/24)

How to count days excluding weekends and holidays but start day/end day can be weekends /holidays?

How to count days excluding weekends and holidays in excel. However, start day and end day can be weekends or holidays.
I have tried Networkdays function in excel using MAC. I also tried workdays function. And, i am new to this forum. Let me know if you are not able to understand anything.
Start Date(E) End Date (F)
2019-07-20 - 2019-08-01
2019-08-04 - 2019-08-06
2019-08-05 - 2019-08-07
2019-08-02 - 2019-08-07
2019-08-14 - 2019-08-20
Holiday list
Date(K) Description Day
8/12/19 - Eid - Monday
8/15/19 - Independence Day - Thursday
Excel formula:
= NETWORKDAYS(E2,F2,$K$7:$K$27)
Start date: Column E, End date: Column F, Holiday list: Column H
output expected output
9 8
2 1
3 1
4 2
4 2
Try using NETWORKDAYS.INTL to make sure that your weekend days are set to fall on Saturdays and Sundays.
For example:
=NETWORKDAYS.INTL(E2+1,F2-1,1,$H$2:$H$3)
Result:

Excel date values compute incorrectly

I am trying to create an excel sheet where each line contains a date/time field for each 15 minute interval for the entire year. I put "00:15:00" in A1 and "1/1/2014" in A2 and "=A2+$A$1" in A3. I then copied A3 down enough times to go thru the year. I set column B equal to col A. I set the format in col A to Short Date and col B to Time. Then I converted everything to values. When I do that, all the entries for midnight are not right. For example the entry between Jan 1 and Jan 2, displays as 1/2/2014 and 12:00:00AM. But the actual value is "1/1/2014 12:00:00 AM". This value is incorrect, it is 24 hours off. What's going on here? How can I fix it?
I'm using Office 2010.
It's standard for 12:00 AM to denote the midnight that starts the day. So, in 15-minute increments, 1/1/14 11:45 PM would typically be followed by 1/2/14 12:00 AM, followed by 1/2/14 12:15 AM.

add hours in excel based on 8 hrs

In my excel I have the project status in hours only .
it means
M1 4 hrs
M2 6 hrs
M3 10 hrs
M4 3 hrs
I have to create a excel so that if I give a start date all the simillar dates needs to be calculated based on 8 hrs working time.
for example if my start date 09/01/2010 (this is the date entered by me)(mm/dd/yyyy)
Start Date End Date
M1 09/01/2010 09/01/2010 (4 hrs)
M2 09/01/2010 09/02/2010 (6 hrs so talking 2 hrs from 09/02/2010)
M3 09/02/2010 09/03/2010 (6 hrs from 9/2/2010 and 4 hrs from 9/3/2010)
M4 09/03/2010 09/03/2010 (3 hrs from 9/3/2010)
Please any one can give me a suggestion.
Thanks,

You have to know that dates and time in xl are stored in days since jan-1-1900 (or any fixed reference date, it does really matter which one). This allows easy addition/subtraction.
From that you can deduct that 1 day has a value of 1, and therefore 1 hour has a value of 1/24.
To test this, enter any date or time in cell, then clear cell the format.
Once you get this, you can solve any problem.
Example:
A B C
Start Date End Date Total Hours
9/15/2010 1:32 9/16/2010 1:32 24:00
9/15/2010 1:32 9/15/2010 13:32 12:00
9/15/2010 1:32 9/15/2010 7:32 06:00
9/15/2010 1:32 9/15/2010 8:44 07:12
C Cell have formula: =b2-a2+IF(a2>b2,1)
End Date - Start Date + IF(Start Date > End Date,1)
I can't attach the picture for some reason
