# Calculating Business Hours

Apr 23, 2008
I use this formula at work to calculate business hours from Mon-Fri:

=IF(OR(L10="",L11=""),"",(NETWORKDAYS(L10,L11,$N$2:$N$23)-1)*($Q$3-$Q$2)+IF(OR(ISNUMBER(MATCH(INT(L11),$N$2:$N$23,0)),WEEKDAY(L11,2)>5),$Q$3,MEDIAN(MOD(L11,1),$Q$3,$Q$2))-IF(OR(ISNUMBER(MATCH(INT(L10),$N$2:$N$23,0)),WEEKDAY(L10,2)>5),$Q$2,MEDIAN(MOD(L10,1),$Q$3,$Q$2)))

where Q3= business start time 8.30am

where Q2= business end time 5.30pm

thus the difference between 18-Apr-08 16:30 and 21-Apr-08 13:30 is 6 hours.

I now need to adapt this formula for another Department that also works on Saturday from 8.30am to 5.30pm.

I'm trying to find a formula for calculating the number of business hours a service request may be open; this request may have been opened and even closed outside of business hours. I found a formula that appears to be working:

=(NETWORKDAYS(StartDate&TimeCell,StopDate&TimeCell,holidays)-1)*(CloseTimeColumnLetter$CloseTimeRowNumber-OpenTimeColumnLetter$OpenTimeRowNumber)+IF(NETWORKDAYS(StopDate&TimeCell,StopDate&TimeCell,holidays),MEDIAN(MOD(StopDate&TimeCell,1),CloseTimeColumnLetter$CloseTimeRowNumber, OpenTimeColumnLetter$OpenTimeRowNumber),CloseTimeColumnLetter$CloseTimeRowNumber)-MEDIAN(NETWORKDAYS(StartDate&TimeCell,StartDate&TimeCell,holidays)*MOD(StartDate&TimeCell,1),

CloseTimeColumnLetter$CloseTimeRowNumber, OpenTimeColumnLetter$OpenTimeRowNumber)

What I don't know is HOW it works, I don't know what any of those formula's mean (with the exception of NETWORKDAYS). I'm trying to "show my work".

I am using the following formula to calculate business hours.

=(NETWORKDAYS(R9,T9)-1)*("17:00"-"08:00")+IF(NETWORKDAYS(R9,T9),MEDIAN(MOD(T9,1),"17:00","08:00"),"17:00")-MEDIAN(NETWORKDAYS(R9,T9)*MOD(R9,1),"17:00","08:00")

The business hours considered here is 8AM - 5PM, Start time in R9 and End time in T9. Now the problem is its calculating the correct value when the days are same, for e.g.,

Condition 1

When I am giving "31 March 2009 15:00:00" as start time (R9) and "31 March 2009 23:00:00" in end time (T9), I am getting the correct value. i.e, "2:00:00"

Condition 2

While giving "31 March 2009 16:00:00" as start time and "01 April 2009 09:00:00" as end time I am getting a value of "1:00:00", actually the value should be "3:00:00".

I want to write a macro to add business hours to a datetime value, excluding weekends, non-working hours and holidays.

e.g., I have a value (datetime) of "18/12/2009 11:30:00 AM", I want to add 10 hours to this, so as to get the result as "19/12/2009 12:30:00 PM".

computing the number of business hours between 2 dates.

Given the following information:

- Business Hours: 8am -5pm (8:00-17:00)

- Business Days: Mon-Fri

- if entry queued falls on a weekend or beyond the business hours, it should count the first hour on the next business hour.

Example: scenario 1 = Starts Sunday, 10am and Ends Monday 9am; count of hours should be 1

scenario 2 = starts on Monday 6pm and ends on Tuesday 10am; count of hours should be 2

i work dispatch at a company and we're trying to track how long it takes for a technician to arrive on-site. my worksheet currently includes the date of call-in (E1) , time of call-in (F1), Service Date (G1), Service Time (H1), among many other field. the easy solution is to use the formula (G1+H1)-(E1+F1), and use the answer as the total amount of time, but the problem is if a customer call in at 3:00 PM and we service them at 9:00 AM the following day, it looks like it took 18 hours to arrive on-site, when in reality, since we close at 5:00 PM and open at 9:00 AM, we only took 2 hours to arrive on-site. is there any formula i can write to account for non-business hours and weekends, or is this a bit above what i should expect from excel?

Where i want add Business Hours/Days to get the Target Date.

Working hours: 8:00 AM to 19:00 PM

Urgency Type:

ND (Maximum 1 Day 11 hours)

3D (Maximum 3 Day 11 hours)

4D (Maximum 4 Day 11 hours)

5D (Maximum 5 Day 11 hours)

Threshhold - 16:30 PM

Weekends to be Excluded.

Holidays to be Excluded based on Country. Say I have 2 countries India and America, where America has holiday on 12/24/2012 but India does not have holiday on that Day. Hence while calculating Tgt date, India should be calculated normally, for America holiday date need to excluded(There will be a Holiday table based on the countries, not limited to 2 countries).

ex: 1) A ticket opened at 12/26/2012 8:56 AM; Target date will be 12/26/2012 19:00, in this case its 1 day 10:04 hours added to the Opened Time.

2) A ticket opened at 12/26/2012 16:56 PM; Target date will be 12/29/2012 19:00, in this case ticket opened after threshold time of 16:30, Technically ticket should start from next day i.e 12/28/2012 8:00 AM and 1 day 11 hours added to this date.

3) A ticket opened at 12/26/2012 7:56 AM(Before the begin of Working hours); Target date will be 12/26/2012 19:00, in this case its 1 day 11:00 hours added to the Opened Time.

4) A ticket opened at 12/21/2012 17:56 PM(After Threshold time); Target date will be 12/24/2012 19:00, in this case its 1 day 11:00 hours added to the Opened Time. If the above ticket belonged to America, then holiday dates(both 24 & 25) need to be skipped and Tgt date will be 12/27/2012 19:00.

Here is the Sample Data

Country

Ticket

Start Date/ Time

Tgt Date/Time

Expected Tgt Date/ Time

America

ID000123

12/21/2012 18:20

[code]....

I need results to be appear in the "Tgt Date/Time" column. I have also provided results in "Expected Tgt Date/ Time".

I need to do an hour calculation on two cells which have dates and times in both. the first cell is a call that we get from a customer and the second is the date and time in which that call is closed by us...meaning that call is complete.

I need to calculate how much time in hours did it take us to complete that call for the customer. I need this calculation to respect our business hours of Monday to Friday 8am-5pm and closed on Saturdays and Sundays.

here are some examples.

from - 2/12/2004 13:00 (thursday)

to - 2/13/2004 9:00 (friday)

answer should be 5 hours

from - 2/13/2004 14:00 (friday)

to - 2/16/2004 10:00 (monday)

answer should be 5 hours

writing a formula that would result in my organizations' business fiscal year.

Assuming the fiscal year is 2008, the quarters are as follows:

1st QTR = 7/2007 - 9/2007

2nd QTR = 10/2007 - 12/2007

3rd QTR = 1/2008 - 3/2008

4th QTR = 4/2008 - 6/2008

When 7/1/2007 is entered, the result should be Q1-2008

10/20/2007, Q2-2008 and so forth.

What calculation would I enter in a results cell if I wanted to find the delta between 2 times in date format that repersent just the business hours of 8am-5pm, therefore excluding after hours and weekends.

eg.

Date 1 Date 2 Result Time

23/07/07 8:00 24/07/07 14:55 15:55

So far I can't get the caluclation that will compensate for the after hours and week ends.

I've being trying t calculate an excel formula to work out a order turnaround time based on opening hours.

Example: The store is open from 8 am to 6pm monday to friday, I need to get a formula to work out how long it took from the time the order was logged until it was completed, during the course of the working day - this works fine but if the order was received on 06/12/07 at 5:20 pm then was finally completed by 7/12/07 at 11:55 the next day I need to figure out how to take into consideration of non working hours during that time. (time from 6pm to 8 am next day

example 2 - if order was sent on the 06/12/07 at 01:30pm and completed at 06/12/07 4:30 then I know its taken 3 hours to complete

example 3 - if the order was sent on the 06/12/07 at 5pm and completed next day at 07/12/07 at 10am - then I know it took 3 hours to complete

It should be deplaying dates of weekly days in Monday, Wednesday and Friday excluding sundays. Or Tuesday, Thursday Saturday excluding Sunday. e.g

Mondays, Wednesdays and Fridays of June

June 1, 2006

June 3, 2006

June 6, 2006

Tuesdays, Thursdays and Saturdays of June

June 2, 2006

June 5, 2006

June 7, 2006

This should be happening after entering any date on the first cell of the List and should accommodate up to 3 months

I have been working on a timesheet but the problem I have come across is calculating actual hours worked only in the core hours and any work outside the core hours is calculated in the outside hours column. A standard work day is 7.6 hours working between 8.30am and 5.00pm. However if someone was to commence work either before 6am or after 8pm this is outside of core hours. I have attached an example of my timesheet for you to see what I am talking about.

I have a requirement of calculating time spent on ticket, basically a difference between the time a ticket was logged and when it was resolved.

First, working days are Saturday through Wednesday, i.e weekends are Thursday & Friday.

Second, there are different resolver groups or teams which work on a ticket. These teams have different working hours, some work from 07:30 to 15:30 on weekdays, and others work 24/7. Each ticket will be assigned only to one resolver group.I also need to consider holidays.

So, my requirement is to check the resolver group for each ticket, and decide the working hours based on it. After this check has to be done for holidays, and then difference between logged time and resolved time needs to caluculated in minutes.

Tickets can be logged at any time of the day / week, it may not always be logged during working hours only. in such cases calculate should consider next business day / hour as the start time.

Raw data for tickets is available in =Sheet1!$A$1:$E$21

I am trying to set up a time sheet for staff where it calculates hours worked in and outside of core hours. I can do a calculation to work out what they have worked in and out of core hours providing that part of their time starts of finishes in core times. The problem I am having is when some one works only outside core hours. Our core hours are 6am to 6pm. The problem is when they work from say 7pm to 1am. This is irregular work paid as overtime not shift work.

I can do the timesheet formula for adding the hours worked as follows:

Start Finish Total

08:45 17:15 8.5

However, it doesn't work when I fill in a whole week work of hours in this format:

Start Finish Total

08:45 17:15 08:30

It works on a daily basis, but when total hours exceeds 24, the formula get's all mixed up - how to I format the total column to account for every 5 minutes worked, which you can't do when converting to decimal??

This may seem like an odd request... I recently received a protected worksheet that I entered my date of birth into, and it told me how long (if I pressed F9) I had been alive in y/m/w/d/m/s etc. I was wanting to do a similar spreadsheet to show how long I had stopped smoking for, and a running total of how much I was saving, but I couldn't look at the spreadsheet for help. The stop time was 01/06/08 - 05:00am GMT, up until present, and buying cigarettes I was spending £0.00004166666 per second. Is it possible to create such formulas?

Example: In cells A1:A10 random number between 0 & say 20, need to sum ABOVE 8 = (calculating overtime hours)

E.g.

A1 = 0

A2 = 8

A3 = 8

A4 = 10 (giving 2)

A5 = 12 (giving 4)

A6 = 5

A7 = 13.5 (giving 5.5)

A8 = 8

A9 = 0

A10 = 16 (giving 8)

A11 = (Total overtime above 8 hours) 2+4+5.5+8 = 19.5

Need to be able to increase rows and drag across.

I'm trying to calculate shift working hours without using dates.

The scenario is

Cell A1 = Start Time

Cell A2 = Start Time

Cell A3 = Break Time

Basically I want the output to calculate hours worked between:-

0000 and 0600 as a total in cell A4

0600 and 1800 as a total in cell A5

1800 and 0000 as a total in cell A6

Then if the value of A5 is greater than A3, subtract A3, but if the value of A5 is less than the value of A3, A5 should be zero and the remainder of the value of A3 subtracted from A4 (or A6) depending which has a value.

I thought I had everything worked out with this timesheet but I've discovered one more problem.

Weekly Timesheet.xlsx

The total overtime hours needs to show that anything over 40 hours in the Total Regular Hours cell is overtime. And it also needs to show only up to 40 hours in the Total Regular Hours cell.
