# Subtract X Working Hours From Date & Time

Jun 20, 2008

I am trying to subtract 8 hours from a date/time. What I need to do is to capture that lead time using only weekdays, and working hours of 8am-5pm.

For example:

Date/Time

Subtracting 8 hours from this scenario would give me
6/20/2008 10:18AM (friday)

## Calculating Elapsed Time,respecting Working Hours.

May 1, 2009

I am looking for a formula to calculate time from one date and time to another. The only catch is I only want it to use times during specific times.

Example

Start 5/1 8am and end 5/2 8am. The working hours are from 7am until 4pm and from 8pm till 5am. In this example the solution should be 17 hours.

How do I set up a formula to respect only working hours (also excluding weekends except for Saturday early am from midnight until 5am.

Sorry if this is confusing, I am trying to use IF statements but I’m fighting a losing battle.

## Calculating Task Completion Time In Working Hours

Oct 15, 2007

The below is for Excel 2003.

I want to set up a spreadsheet that can show my work is completed within a service level agreement, based on working hours of 9-5 Monday-Saturday.

I want to be able, for example, to log that a piece of work is reported at 09:00 on a Monday and completed at 10:00 on Monday and for excel to calculate that as 1 hour until completion. Fine so far. But what if that job was closed at 10:00 two days later? Based on an 8 hour working day, that should be 17 hours.

And what if a bit of work comes in at 17:00 on the Saturday. No one works the Sunday. Say the job is completed at 10:00 on the Monday. that should calculate as 1 hour to completion.

The SLA I'm setting is 4 hours.

## Adding Time More Than 24 Hours To Date Time Stamp?

May 30, 2012

I want to add hours to a date-time cell to get result in date-time.

Format of cell A1 is d/m/yy h:mm AM/PM
Format of cell A2 is General
Format of cell A3 is d/m/yy h:mm AM/PM

I want to add A2 (number of hours) to A1 to give A3.

The formula I used is A3=A1+Time(A2,0,0)

The formula works perfectly fine when A2 is less than 24, but when A2 is more than 24, the date doesn't get changed.

## Time Conversion: Convert A Time From Hours/Minutes To Hours/Tenths

Oct 10, 2009

When I am converting a time from Hours/Minutes to Hours/Tenths, Excel is not converting it consitantely. EXAMPLE: 1:15 = 1.25. When I format the cell to present only one place past the decimal point, sometimes the cell will round up to 1.3, and other times it will round down to 1.2. What am I missing?

## 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 ",""))

## Add X Hours By Condition To Date & Time

Feb 22, 2008

Column 1: Date Call is received by helpdesk
Column 2: Time Call is received by helpdesk
Column 3: Drop-down list indicating Priority of call (High,Medium,Low)

In Column 4 I want to enter a formula that adds working hours only to the date and time entered in Columns 1 & 2. The time added will vary depending on what is entered in Column 3 (e.g.: if priority is High add 1 hour, Medium add 2 hours, Low add 3 hours). The working hours i need to adhere to are 09:00-17:00, Monday-Friday.

## 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?

## Calculate Date/time Format Over 24 Hours

Nov 22, 2006

I need to calculate the difference between two cells that are formated like this: 11/10/2006 13:00. Simple subtract only works when the date hasn't changed (the subtract formula seems to focus on the time and ignore the date).

I found a formula that will work, but the results are in regular numbers, I need the hh:mm format and if I change the format of the result column, the time displayed is wrong.

The formula is=((B2-A2)*1440)/60)

If my result is 122.6 in regular numbers, when I convert to hh:mm I get 14:00.

Is there a better way to do this? Also, is there a way to eliminate weekend & holiday hours from the calculation? This is not as important as getting the results to calculate correctly in the hh:mm format.

## Check Date & Time For Missing Hours

Aug 7, 2007

I have a column A with some dates at this format "dd-mm-yyyy hh-mm".
In this list, some hours are missing, and I don't know which ones.

In order to find the missing hours, I created an additional column B, displaying all the hours, this way:
B1=01-01-2006 00:00:00
o
B1=A1

And then : B2=B1+"01:00:00"

Then, in column C, I compare both columns A and B:
C1=IF(Value(B1)=Value(B2),ok,missing)

As a result, I first get some "ok", and then more and more "missing" statements, even though the dates look the same.

I checked the numerical values of my dates. At the first "missing" statement, I saw that there is a slight difference in the numerical values, at small decimals...

Can you tell me how to define my date /time in a good way, in order to avoid this kind of problems, please?
(I could take the int part of the numbers, but this could lead to further errors, so I prefer to define my dates in the right way, from the beginning).

## Calculating Day And Night Shift Hours From Date / Time

Dec 22, 2009

I want to find the hours worked in day shift and night shift. Day shift is from 06:30 to 18:30 and night shift is from 18:30 to 06:30. Listed below is an example of my date/times.

Note that the night shift carries over to the next day.

Start/Finish
21/12/09 07:00 to21/12/09 11:09
21/12/09 07:46 to21/12/09 14:41

## Macro To Recognize Date That Is 48 Hours Before Current Time

Feb 15, 2012

I have a spreadsheet that contains a list of names/numbers/dates and I have to manually go through the list each day highlighting the row if it contains a date that is more than 48 hours old. How to accomplish this in a macro? Example:

xxxx........555-555-5555...........5555555............2/12/12
xxxx........444-444-4444...........4444444............2/15/12
xxxx........123-456-7890...........1234567............2/10/12

That is the layout of the spreadsheet so I would have to manually highlight rows 2 and 4 because the date in Column D is greater than 48 hours ago. The range is A1:D25 and the cells are changed/updated daily.

## Separate Hours Based On Time / Date / Holidays

Jan 9, 2013

I calculate total labor hours entered into a CRM system and use it for various reports, but it's incredibly inaccurate for the following reasons:

Any labor put in between 6pm EST and 8am EST from Mon-Fri is considered "on call"All labor from Friday 6:01pm - Monday 7:59am is considered "on call"Labor entered on a company recognized holiday is considered "on call"Not every employee takes call

So, what I'm trying to do is take the total labor and pull out only the hours entered outside of the criteria above. If it were simply based on time during the week, i'd be fine, but I have no clue how to do everything else.

In the end, my new labor hours would be split into "Business Hrs. Labor" and "On Call" labor.
