# Formula To Work Out A Variance Between Two Times (subtracting Time)

Apr 8, 2007

formula to work out a variance between two times

Using the 24hr time format in cell a1 i have a start time of 10:43 and in cell b1
i have an estimated time i think a job should take in this case 30 minutes and in cell c1 i have the actual time that job was finished in this case 11:07 and in cell d1 i have a variance between the two times which in this case would be saving me 6 minutes

## Subtracting Time (finding The Difference Between Times)

Dec 8, 2009

I am having trouble finding the difference between times. I have two cells, A1, A2. Times will be placed in there each day. A1 will have the first time and A2 will have a later time that day. i.e. A1 12:25AM, A2 2:45AM. A3 would have the formula. In this case I am looking for an answer of 2:00 (2hrs).

My second issue will be times when I have A1 11:20pm and A2 1:20am. I can't seem to get it to work.

## Some Times If I Do A =if( ) Formula It Doesn't Work

Mar 12, 2008

What am I doing wrong here. Some times if I do a =if( ) formula it doesn't work. For example, look at the attached picture. Cell K63 should say "End of Run". But it doesn't, What gives?

Also I have had before where i do =IF(X62>\$O\$2,"End of Run", 0) (and \$O\$2 =81) and the cell when X62 is 81, not greater than. I know I can to >=, but thats not what I am doing.

## Time Variance

Apr 2, 2008

Column A has a time (no date)
Column B VLooks-up a value from a separate sheet per country, so it pulls through a the variance [-11 to +13] from UTC (GMT) time dependent on country.
All other data is irrelevant.
Let's say Column C has following formula: A2+B2/24.

This works where the time result (new time) is on the same day, but as soon as it crosses over midnight, it buggers up.

What I'm needing to do is take a list of events (server time/GMT) and convert them to the local time from where the event was triggered based on source country.

## Subtracting Times :: Next Day ..

Jan 22, 2009

Start time is 2300 in A1
End time is 0100 (the next day) in B1
Difference should read 120 minutes in C1

I know this is possible, I think I've thought myself into circles on something that shouldn't be hard. Everything I've tried is giving me negative numbers and at some point I've tried using the +1 behind B1 to represent the next day.

Here are some of the formulas I've found throughout various posts and used.

=B1-A1+IF(A1>B1,1)
=B1+(A1>B1+1)-A2
=IF(A1

## Calculating Time Variance

Jan 26, 2009

I'm trying to calculate the variance between planned date & time of arrival vs actual date & time of arrival.

I attach the workbook as am a bit useless at explaining myself....

What I've done is in H14 subtract the actual date of arrival (F14) from planned date of arrival (C14). This result is the only way I could think of dealing with crossing over midnight. As a result I14 should subtract the actual time of arrival (E14) from planned time of arrival (B14):

=SUM(E14-B14,H14)

This method works well when the arrival was later than expected but doesn't work if the arrival was sooner than expected.

Sep 8, 2009

I'm making a table for myself to keep an eye on my hours worked every week. What i want is to be able to enter the start time and the end time and for Excel to find the time difference inbetween (not numerical mathematical difference) also i need to subtract a half hour from the time entered for monday thru thurs.

## Subtracting Times :: Timesheet

Jul 30, 2008

I am making a timesheet

I have

Start Time, End Time, Break, Hours Worked. Then on the right hand side of my spreadsheet I started playing around with the current time etc.

I want to work out the time left in a working day(like a countdown), based on a variable number of hours of work in a day (here it is 7 hours) excl. breaksie. 7+breaktimeso I need 7+break - 'hours worked' to get hours and mins left
I worked out how to get hours worked easily enough,

=J58-LOOKUP(TODAY(),A:A,D:D)-LOOKUP(TODAY(),A:A,B:B)
where J58 is a cell that has the current time in it and D and B are the columns with the break time and start time in them.

Hours Worked01:59:48Current Time11:49:4807:00:00Break time: 00:30:0007:30:00

I am trying to subtract the hours worked (1:59:48 in this case) from 7:30:00. The hours worked can be updated every second using F9.

I know it's something to do with negativer times because of dates etc but I don't know what to do to make it work.

## Work Accurately With Times To Calculate The Work Progress Of The People In The Workshop

Mar 3, 2009

In a project i am compiling i need to work accurately with times to calculate the work progress of the people in the workshop thus....here goes....

I have in work book #1 (7) sheets mon to fri + complete week + a sheet where all job numbers are collected.

From monday to friday the workmen log their times as a start time and a end time. This has to be then calculated to a total hours:mins spent per job, wich in turn then has to be calculated to a total hours:mins spent per day. And the on the complete week sheet recalculated as a total time worked per week.

## Subtracting Hours In A Work Schedule

Aug 29, 2009

I am working on a monthly employee work schedule that has 2 stores. All employees work at both stores and the boss wants 2 separate schedules.

I have attached what I have started, which at the moment I am stuck.

I would like to have the Row 5 total hours to always reflect (subtract) a 30 minute lunch. I know it would be easier to have another column, but the boss wants it this way,

I also need the total hours in column H to reflect the total of each day (with the subtracted lunch break). In this column I am having the figures turn red if over 40 hours and green if it under 40 hours.

With having 2 stores with the employees working at both, I need to somehow have the hours of the employees add up from one store to the other (a running total, if you will).

Lastly, if I have an employee not scheduled for a day or need to put other data such as, VAC, HOL or blank cell etc in a cell, how can I get this to work and not have the formula go nuts when it is not in a time format.

## Subtracting Times :: From Input Minutes

May 30, 2008

I need to subtract one cell from another. I want to subtract an input value (minutes) from a cell that contains a calculated value of hours & minutes. The calculated cell is custom formated h:mm. I prefer the input be a simple numeric value. The answer needs to be in the h:mm.

## Vba Type Mismatch When Subtracting Dates/times

Sep 27, 2006

Does anyone know why I get a type mismatch on the following? I am trying to subtract one time from the other to get the total hours worked.

Sub WorkedHours()
Dim vStart, vEnd As Date
Dim vHours As Integer

vStart = "11/09/06 22:00"
vEnd = "11/09/06 23:30"

vHours = (vEnd - vStart) * 24

End Sub

## Calculating Work Time Formula?

Jul 11, 2013

I'd like a calculation that gives me a total of 7.50 hours instead of 8:00 hours (I'm hoping to add up the time worked into a meaningful hour:minute format)

## Enter Total Time And Subtracting From Daily Time

Apr 9, 2012

Any way to enter in a total amount of time and then subtract it from a time shown. So for example:

I want to enter in a time of 26 hours, 10 minutes and 2 seconds: 72:10:02

I cannot find a format that allows me to enter the hours in excess of 24

Then I want to subtract it from a time of the day which will be entered as AM/PM: 02:40:02 AM

Then I want to show the result as a time of day: 00:30:00 AM

Lastly, I want to also show the amount of days adjustment: -1d, 00:03:00 AM

How this can be done through cell formulas?

## Time Difference Formula Where Both Times In 1 Cell

Aug 14, 2007

I need some IF formula I believe that will yield an answer between 1 - 5. I'm not swavey enough with these things to figure this one out... trust me I tried and it keeps getting more confusing for me.

If the time worked is between certain time criteria then it would equal 1 - 5 depending on the time.

Example: If I work between the hours of 5am and 1pm then I would be in the Open/Mid range and would need to equal 2. If I only worked a few hours and my hours fell only between the Mid range then it would equal 3.

Then based on that... It would automatically fill in on the deployment charts... My name would show up on the Open and Mid Deployments under the task chosen for me to do that day.

I've attached a small sample of what I am looking for to kind of help show what I need. The highlighted areas are the areas I'm not sure how to do.

## Formula For Date And Time Difference Using 8am-5pm Work Hours

Oct 22, 2008

I need to enter a formula that calculates the time a report is received from the time it was recorded in our database. therefore, it needs to exclude non working hours. here are the fields:

A1 2008/10/10 16:30
B1 2008/10/11 09:30
C1 8:00
D1 17:00

B1 = reported recorded in db
C1 = work day start time
D1 work day end time

Where the answer should = 2 hours.

I am not an experienced excel user and so far the only formula I have now is: =TEXT(B1-A1, "d:hh:mm")

And how do I account for weekends?

## Formula For Budget Variance

May 18, 2009

finding a way to compare the two budgets i.e 08/09 and 09/10 and if a new cost centre appears in 09/10 it will bring a yes in column G(New cc) and if the Cost Centre already exist in 08/09 it will bring a blank--but in both cases i want a variance in the next column H i.e 09/10 less 08/09.

## Formula To Count Number Of Times A Occurs Between Time Periods

Nov 30, 2013

I am attempting to create a formula that will count the number of times, lets say letter A, occurs in column E. However, the tricky part that I have been confused on is that I only want to count how many times A occurs between each hour of the day. I need to count number of times "A" occurs between each hour of the day for the entire month.

My Worksheet looks as such: Column A contains the dates for the month of November, Column B contains times that random instances occur, Column C is not important, Column E contains a Letter A-N that pertains to what occurred at a time in column B. SO, Column B and column E coordinate with each other.

Here is an example. Column A - Cell A1 - 11/01/2013 , A2 - 11/02/2013, A3 - 11/03/2013.
Column B - Cell B1 - 12:01 AM , Cell B2 - 14:03 , Cell B3 - 15:23
Column C - Cell E1 - A , Cell E2 - A, Cell E3 - B

So I would like Column F to display that between 12:00 - 12:59 Am there was X number of times the letter A occurred throughout the entire month.

## Time Subtracting

Jan 30, 2007

I have three cells... A1= entry time & H1 exit time...both are formated as such Custom #0":"00 so i don't have to enter the colon with every entry and exit time... my issue is that i want the third cell to count the minutes in cell A1 & H1...

## Subtracting Time

Feb 15, 2008

I saw this answered somewhere on here but really didn't understand.

I'm trying to set up a sheet for my hours worked for the week.

I have the total per day in H2 through H6 In I2 through I6 I have an accumulative total for the days, so assuming I work 8 hours a day, I2 would be 8:00 I3 would be 16:00 I4 would be 24:00.

In J2 through J5, I'd like to have the weekly accululative worked hours subtracted from 40 so that the total is what I have left work until I hit 40.

## Subtracting One Time From Another ...

Jun 25, 2009

Here's a simple one guys. How do I subtract 7:30 AM from 4:00 PM to give me 8.5 hours? At the moment it returns either 8:30 AM or (formatted Number - General):

0.3541667

## Subtracting Time If A Certain Time Frame

Mar 12, 2009

I need 15 minutes removed from a difference in time, if the time span falls over 9:00 am through 9:15 am.

I'm inputting time like 8:30:00 in A1 and 10:30:00 in A2, then calculating the difference in A3 (2:00:00). Is there a way to remove 15 minutes from that 2:00:00, since it falls over 9 to 9:15?

## Formula To Calculate Speed Knowing Distance, Destination Time And Checkpoint Times

Dec 2, 2008

On my spreadsheet i have a bunch of variables:

A1 = Arrival time at Checkpoint 1 - 5:53:08
A2 = Time to destination from Checkpoint 1 - 1:10:18

B1 = Arrival time at Checkpoint 2 - 6:00:56
B2 = Time to destination from Checkpoint - 1:02:30

C1 = Total distance from Start - 2.83
C2 = Arrival Time at Destination - =SUM(A1,A2)

D1 = Speed determined from the other variables
D1 is SUPPOSED to equal 25.00

It also is where I am stumped!!

Not only can I not figure out the math but also how to format the function to get the right answer.

ps: Arrival Time at Destination is only included in case it would be useful to find the answer!

## Subtracting Time Between Two Dates

## Subtracting Time - From Before Midnight To Next Day

Jun 18, 2012

I am trying to work out the response times to an event that my staff attend ( such as a fire alarm)

In C1 will be the time the event was called in, 23:55
In E1 will be the arrival time, 23:59
In F1 I want to show the time taken to arrive on site (response time)

This seems straightforward until the arrival time goes into the next day, such as 00:05 and this is when I have the problem

To make it more complicated, sometimes there is no need for an arrival time to be entered for some events ,with the end user leaving it blank or putting "NA" or "na" etc into the cell

I have tried the below formula which works to a point but leave me with an ######### error if the time is after midnight

=IF(E1="NA",0,IF(E1="n/a",0,E1-C1))

Jan 23, 2008

I have the formula in my spreadsheet to compute time. It works only if the time in B1 is greater then the time in A1. I would to know if there is a formula to compute time with either negative or postive answer. For example if a carrier was set to load their papers at 12:02pm and ended up loading early at 11:50am I would like the result in C1 to be -12 or (12).

Currently I am using the formula: =HOUR(B1-A1)*6+MINUTE(B1-A1). Like I said, it is all good until someone loads early and then I get a "#NUM!"

Are there any other formula's that I can use or is there a simple modification to the formula I am using?

## Subtracting A Field That Has Time

Jan 21, 2010

I have some intraday date that looks like this, hope the formatting comes thru when i post this....anyhow, the second column is TIME (ie 15:25 15:30, etc...5 minute time intervals for SP500 stock data. I want to have a column that simply subtracts row 2 column b (time column) from row 1 column b.....when i do this i get a #value....I know this must be possible to get a result i need....ie 15:30 - 15:25 = 5

Do i need to reformat the TIME column into something different? ....

## Losing A Minute When Subtracting Time?

Jan 6, 2014

In cell L7 I have (80/60)/24 and formatted h:mm to get 1:20. In cell M11 I have 1:00 (h:mm). In cell M12 I have L7-M11 and get the result 0:19. Why I'm losing a minute and not getting the result 0:20?

## Subtracting Time/date Using NOW Function

Oct 6, 2009

I have a working week that starts at 07:00 on a Monday morning and finishes at 14:30 on a Friday afternoon.

For planning purposes I need to know at any given point how many working hours are left. The reason for this is so that I can multiply that figure by the amount of Engineers available which will give me the amount of Man Hrs left in the week.

For example - if it is 11:00am on the Tuesday, how many working hours are left ....

## Subtracting Time (in Numbers) To Decimal

Oct 21, 2009

How can I add/subtract time entered as 1830 to give a decimal value?

Start=1830
Finish=2000
Time between = 1.5

Also, how can I convert time as 1830 (24hr) to 12hr time? ie. 0630.
