# Computing Business Hours Between Dates?

Jan 9, 2014

computing the number of business hours between 2 dates.

Given the following information:
- Business Hours: 8am -5pm (8:00-17:00)
- 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

## Calculate Hours Between Date And Time Within Business Hours?

Apr 4, 2013

find a formula that will calculate the hours between the two below values but only take in to consideration the business hours (from 9 to 17) and exclude any weekends?

08/03/2013 13:32:00
02/04/2013 09:32:50

Mar 31, 2009

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".

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.

Dec 18, 2009

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".

## Time/date Tracking Only During Business Hours

Mar 19, 2007

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?

## Calculating Business Hours Of Service Request

Apr 12, 2012

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".

Dec 24, 2012

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".

## Subtracting Business Hours From A Data And Time Value

Jun 26, 2008

I am trying to subtract 12 business hours from a date/time stamp. It has to be during working hours however which are 8AM - 5PM, Monday-Friday.

For example if my value is 6/23/2008 9AM

Subtracting 12 business hours would give me 6/19/2008 3PM.

## CALCULATION TAKING BUSINESS HOURS INTO CONSIDERATION

Feb 18, 2004

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)

from - 2/13/2004 14:00 (friday)
to - 2/16/2004 10:00 (monday)

## Calculation Of Business Hours Excluding Sundays And Holidays?

Jan 29, 2014

I want to calculate the time in hours between to dates excluding non-working hours and sundays and holidays.

My office timings: 10:00am to 05:30pm Saturday is working day. Only sundays and holidays to be excluded.

## Date/Time Calculation For WeekEnds/After Business Hours

Jul 23, 2007

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.

## Calculate Elapsed Time Based On Business Hours

Dec 8, 2007

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

## Calculate Time Spent On Ticket Minus Non-Business Hours?

Jun 6, 2012

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

Feb 26, 2014

How would I write a function to give me the last ten business dates moving horizontally from today's date with yesterdays date the being the last date? So if A1 is 2/26/14, how would I populate B1-B10 with wanting B10 to be 2/25/14 and moving backwards but only with business dates?

## Difference Between Dates And Times In Days , Hours Mins ( Working Hours )

Mar 2, 2010

The below formulae allows me to see the difference between two dates and only returns the difference in working hours ie :
Difference between
02/02/2010 08:00 & 03/02/2010 08:00 is 16 Hours 0 Minutes

=(INT(A3)-INT(C6))+MAX(MOD(A3,1)-MAX(MOD(C6,1)))

The following displays it in the Hrs and Mins format

=TEXT(B15,"[h]")&" Hour"&IF(OR(TEXT(B15,"[h]")+0=0,TEXT(B15,"[h]")+0>1),"s "," ")&MINUTE(B15)&" Minute"&IF(MINUTE(B15)1,"s ",""))

## Calculate Future Dates On The Business Day Preceeding The 15th Of Each Month

Sep 16, 2009

Sometimes my due dates need to be on the 15th of the month, for which DLL and Donkey gave me: =DATE(YEAR(TODAY()), MONTH(TODAY()) + (DAY(TODAY()) > 15), 15)

This works great except sometimes the 15th is on a Sunday which means I need the result to be the 13th, and sometimes it's on a Saturday which means I need the result to be the 14th. FYI: I am a n00b..

## Automatically Highlight Fields With Dates Older Than 5 Business Days?

Dec 17, 2012

I have columns of dates and I'm looking to automatically highlight dates that are older than 5 business days from today. Is that conditional formatting?

## Difference Between Dates & Times In Business Days With Time Constraints

Aug 16, 2009

I need to create a spreadsheet that will calculate the difference between two dates and show the result in days. The complicated part is that weekends (Sat and Sun) need to be ignored and any time after 4:30 pm needs to be treated as the next business day. I have been trying to look at similar questions in forum and use the WORKDAYS function with little success.

Example:

A1- 14/08/09 4:40 p.m.
B1- 17/08/09 9:10 a.m.

I need the answer (B1-A1) to show up as 0. But if the time in A1 was changed to 4:20 p.m. than the answer should be 1 day.

## Calculate Hours Between Two Dates

Jan 1, 2010

I would like to calculate the total hours between two dates using a unique formula and without inserting new columns. I have attached an example of the data I'm working with.

## Total Hours Between 2 Dates

Jul 21, 2008

I want to add the numbers of hours in a 4 week period. I have used the following formula (from this site) to total according to month but I don't seem to be able to adapt it to change it to only add hours between 2 dates or for the 28 day period. I thought maybe I should be using a SUMIF but I can't get that happening either.

I have attached a simple file( I think!!)

=SUMPRODUCT((TEXT(\$B\$3:\$B\$61,"mm/yy")="07/07")*(\$C\$3:\$D\$61))

Feb 15, 2007

I'm having great difficulty adding hours to dates in Excel. In cell A1 I have a number which is calculated from a formula, it will normally return whole number values between 1 and 100. In cell A2 I have a start date and time i.e. 14/2/07 06:00:00 in cell A3 I want to add the number in A1 as hours to the date in cell A2. I am using the formula in A3 as =A2+TIME(A1,0,0) it seems to work okay for numbers that don't take the date onto the next day but if I try to add 24 hrs or 48 hrs for example the date still stays the same.

## Add X Hours To Dates And Times

Dec 31, 2007

I receive data from a company I deal with that has the date and time of all of my transactions with them listed in an excel worksheet. Only problem is that the date/time that I receive is not in my timezone, which is a bit of a problem for me!

What I want to do is to be able to adjust the date and time shown in the cell forward by 14 hours, so that the data is shown in the timezone that I am currently in. So the end result for the first line of data in the attached file would end up being 2006-08-11,10:28:51 instead of 2006-08-10,20:28:51.

## Working Hours Between 2 Dates

Mar 3, 2008

I have a spreadsheet with various date fields and next to those time fields. I need to calculate the amount of working hours between the 2 lots of values

for example

Cell A has "22/02/2008"
Cell B has "16:44:00"
Cell J has "25/02/2008"
Cell K has "08:59:00"

The answer i'm looking for is 01:29:00. The working hours are Monday to Friday 07:30 - 16:00. This is what I have so far and it gives me the total hours between the 2 dates but not the working hours. =IF(J10-A10=0,K10-B10,((J10-A10)+(K10-B10))) (Formatted with [h]:mm:ss). I have tried using workingday() but can't get the desired result

## Calculating Working Hours Without Using Dates

Mar 18, 2014

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.

## Formula To Get HOURS From 2 Dates With Time

Jun 30, 2014

How to get the Hours of two different time

A1
27/06/2014 11:30

B1

C1

Ans: Hours of these 2 dates with time.

i just need to get their Hours.

## Calculating Total Hours Between Dates

May 2, 2008

I need to calculate time taken to fix a piece of equipment.

A1 B1
BREAK TIME FIX TIME
4/22/08 23:00 4/23/08 04:00

Should be 5 hours, but i can't find the formula to make it work.

## Countif Of Hours And Mins Not Dates

Mar 17, 2009

I have a data feed that gives a column of cells formated mm/dd/yy hh:mm
These are call entries, what i want to do is count all the occurances each hour, so count all the entries say between 9am and 10am. However the column is very long and holds data for many weeks so i want to be able to ignore the date part of the cell.

For example

3/17/09 9:58
3/18/09 10:58
3/18/09 8:58
3/19/09 8:58
3/19/09 9:58
3/19/09 9:58

So the entries between 9 and 10 are = 3

Ideally i do not want to do text to colums and split out the parts. i would like to leave the source data alone.

## Difference Between Two Dates/times In Hours

Apr 24, 2006

I need the difference between two dates/times field in hours or minutes.

Eg:

A1 B1
1/4/05 10:00 2/4/05 14:30

The result should be 13.5 hours, considering only 8 hrs per day, only business days and 8 to 5 workday.
