# Formula To Calculate The Difference Of Time Between Cells

Feb 17, 2008
I'm working in excel2007:

I want to write a generic formula to calculate the difference of time between cells, the first being a real data point, such as

6/22/2007 8:53

minus a generic constant term using the same date and a given time, 8:30.

So, what I need is something like this:

6/22/2007 8:53 – (same mm/dd/yy @ 8:30)

6/22/2007 12:29 – (same mm/dd/yy @ 8:30)

6/25/2007 11:19 – (same mm/dd/yy @ 8:30)

This may be a bit vague but here goes.

I have to calculate the difference between the start time and end time of a job. The only catch is, how can I avoid calculating "out of hours" time. So, if a job goes from 9am to 9am the next day, I want it to avoid calculating between the hours of 23:30 and 03:30.

Another example is if a job goes from 02:00 to 04:00, I want it to avoid the tim between 02:00 and 03:00.

If there is a difference in days, so the job goes overnight, how do I take that into consideration also.

I've got a time difference from 8:00AM - 12:30PM as 4.30 I'm trying to get the minutes, .30, converted into a 6 minute increment, .5. Is it possible to do this and if so how would it be done? Below is a chart of how the time is converted from 6 minutes increments into decimal form.

6 = 0.1 36 = 0.6

12 = 0.2 42 = 0.7

18 = 0.3 48 = 0.8

24 = 0.4 54 = 0.9

30 = 0.5 60 = 1.0

I am currently usins Excel 2007 and would like to calculate the diferrence in hours and minutes (ideally in decimal e.g 4:30 should be reflected as 4.5) between two date and time groups, excluding the non-working time between 17:00 and 09:00, weekends and holidays. An 8 hour working day is to be used. I have attached a spreadsheet were I tried to achieved the above with little success.

I have two Rows of data. Each row contains a unique Name column and separate columns for Date, Hour and Minute. I would like to calculate the Time difference in Days, Hours and Minutes between the two Dates. I’m not sure if the way I’ve set it up is the most practical. I’ll attach the spreadsheet to better explain.

i've two time constraints with 22:00~6:00 and 6:00~22:00. i'll apply time span to two constraints,calculate time covering on two constraints. it will start at anywhere of 00:00~24:00, time span will be 00:00 ~24:00. i add some formula, a3=start time, b3=end time. time constraints with 22:00~06:00:

=IF(AND(A3<=22/24,B3>=6/24,A3>B3),8/24,IF(AND(A3<6/24,OR(B3>22/24,AND(B3>0,B3<6/24,A3>B3))),IF(B3>=22/24,(B3-22/24)+A3-6/24,(B3+1-22/24)+MOD(6/24-A3,1)),IF(AND(OR(A3>=22/24,A3<B3,A3=0),B3<=6/24),IF(OR(A3=0,A3=1),B3,IF(A3>B3,B3+1-A3,B3-A3)),IF(AND(A3<=22/24,B3<=6/24),MOD(B3-22/24,1),IF(AND(A3>=6/24,B3<=22/24,A3<B3),0,IF(AND(A3>=22/24,B3>=6/24),(1-A3)+6/24,IF(AND(A3<=22/24,B3>22/24),B3-22/24,6/24-A3)))))))

time constraints with 06:00~22:00. :C$3=start time,$B4=end time...............................

I am setting up a time and attendance system.

What I want to do is calculate the overtime that someone has worked but in multiples of 15 minutes.

Example, if someone worked 20 minutes over they would be paid for 15 minutes overtime.

If someone worked 31 minutes over they would be paid 30 minutes overtime.

The possible overtime someone could work in one day is 6 hours.

I want it to return the overtime in decimal numbers (e.g 0.25 for 15 minutes overtime).

I have attached a sample spreadsheet.

I would prefer this to be done in VBA if possible?

I'm trying to do some calculations involving times. I'm using the format [=A2+(A1>A2)-A1] in order to calculate times from one day to the next which avoids negative numbers. This is working well. My problem is now that I'm trying to develop my spreadsheet and am trying to embed this inside an IF statement as the [value_If_True]and I get an error because it doesnt like the leading equals sign inside the IF statement.

Time arithmetic, I have two cells representing a time range.

The first one (say: X1) is formatted using the custom format [h]:mm and contains a certain number of hours and minutes. It gets its value by summing up other cells in the same format. A typical entry could be 98:35 to represent a duration 98 hours and 35 minutes.

The second cell (say: X2) is formatted as a number with 4 decimal places after the comma, and similarily gets its value by summing up other cells in the same format. It also represents a time duration as a number of hours. A typical entry could be 202.7500 to represent a duration of 202 hours and 45 minutes (because 0.75 of an hour is 45 minutes).

I would like to calculate the hour difference between these cells, and display it as hours and minutes. In the example given, the result should be negative, i.e. -104:10.

My first approach was to use the formula X1-X2 and format the result as [h]:mm, but this gives me a #VALUE! error.

I have an excel spreadsheet where you enter the start time and end time for job function. Since some of the times cross midnight, I use the formula J3=IF(I3>H3,I3-H3,1+I3-H3) where I is the end time and H is the start time (format hh:mm). This part works fine, however when I sum column J and change my format to Time 37:38:00 (since it is over 24 hrs), it returns a large number of 2234:48:39 which should be closer to 223:00:00.

I have two sets of data, one is recorded every 5 minutes and the other is every 15 minutes. I am trying to add every 3 cells in the 5 minute column so I can compare it side by side with the 15 minute column. I have tried one of the responses in this forum with placing 0s in 2 cells and then the formula in the third however this does not allow me to compare the 2 sets side by side.

See attachment. In this example, in Column D I want to calculate the percent difference between the numbers in the last 2 columns (Column B and Column C). BUT I want a formula that will automatically update if I were to insert a new column between Column C and Column D. So as a result, new numbers would go in Column D and the percent difference would now be in Column E.

I'm trying to make a formula to calculate the difference in a date between two dates. For exaple, in my business we have a due day for something. So the due date could be Feb 10, we need to know if it was done on time, late, or early. So I've gotten it to display late by doing this: =IF(B2>A2, "Late", (A2-B2)) But then I can't figure out how to incorporate this: =IF(B2=A2, "On Time") or =IF(B2<A2, "Early").

I would like to displaly this all in one cell. So if the due date is Feb 10 and it's turned in Feb 8 it's early, turned in Feb 10 it says on time, turned in Feb 11 it's late. I also tried this but it didn't work: =OR(IF(B2>A2,"Late")*IF(B2=A2,"On Time")*IF(B2<A2,"Early"))

I'm looking for a formula in relation to the calculation of time.What I'm looking for is a way of finding the difference between the time two cells and it displaying it in the number of hours e.g.:

Cell 1__Cell 2__Cell 3

12:00 + 18:30 = 6.5 (it is 6 hours 30 mins but I want it displayed as a number.

1.The attached file shows an example extract of a data extract that has thousands of lines. See the Data Tab.

2.What I need is some time that has passed between two dates in a DDHHMM format

3.What I then need is the top 50 of each of the times (or the longest time past)

4.The column headers will be: WO Number | Contractor Name | Time Calculation â€“ see the various Report tabs

5.The calculations in the Data tab are between the following columns.

a.Difference between Column Z and Column AC

b.Difference between Column AC and Column AD

c.Difference between Column AD and Column AE

d.Difference between Column AE and Column AF

6.Is it possible to show the top 50 only in time?

This report is forming a part of a larger report and all other formulas are already present so I am hoping to keep the file size quite small. The aim is to then hand this over to someone else to just print on a monthly basis depending on the data that gets added with minimum input.

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.

A person spends some time performing various works (work1, work2...) in a day. Each work can be further divided into tasks (task1, task2...).

I need to find the total time spent by the person doing all these activities.

The attached spreadsheet will explain it better.

I am using the following formula in Column E to calculate the difference between an employees start time, and their previous shift end time in order to work out how many hours rest they have had:

=IF(A4=0,"",IF(I4=0,"",MOD(I4-B4,1)))

My Current Formula works fine for same day calculations, but if an employee finishes work at 18:00 on Friday and starts work at 22:00 Saturday night, Excel calculates the Total Rest hours as 04:00, when in fact they have had 28:00 hours rest...

Is there a way of calculating the hours difference between two dates?

I have attached a sample of my spreadsheet to illustrate

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

A1 = report received

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?

I'm looking for a formula that will calculate the difference in times between specific times while working with a 24 hr clock. Please see details below:

E3 provides the start time of 4:00

H3 provides an end time of 15:30

If an employee works betwen the hours of 0:00 (midnight) to 5:59, this is considered DIFF hours and is therefore the number I am seaking. So for the data noted above, the total DIFF hours worked is 2 hours.

I have been asked to make some ammendements to a workbook currently in use.

I have to calculate elapsed time, and my formula is giving me odd results. I have a start time (cell B5), and an end time (cell F5). The formula being used was =IF(F5>0,((F5-B5)*24)) which gave the correct result. The cell is formatted as general. It didn't alot for the situation where the end time has not happened yet.

I changed the formula to =IF(F5>0,((F5-B5)*24),(K5-B5)*24) where cell K5 is the current time. The results are coming out with 6 - 9 decimal places. It makes no sense as I've tried setting the times to be exactly 24 or 48 hours to the minute. I've also tried replacing K5 in the formula to now(),

I want to calculate labour rates as follows:

06:00 to 18:00 std rate $10

18:00 to 06:00 night shift rate $15

I want to be able to type in the hours worked e.g. 11:00 to 19:00 and would expect 7hrs at $10 and 1 hr at $15.
