# Formula To Calculate Time Difference Crossing Midnight

In Excel I have been trying to find an easier way to calculate a time
difference where the times cross midnight. Example:
Start time: 23:50:00
End time: 00:15:00

How would you formulate an equation to determine the duration of time or
differnce between the start and end time?

Hi Guys,
I need help....I am working production scheduling with Start and End time but there is a lunch time and tea time. Is there any formula to calculate Start time to End time with excluding lunch time?
Here is example :

Lunch time :12:00pm to 1:00pm.
Duration Process :6 hours.
Start Time (8:00am)
End time (5:00 pm)

I need a formula to calculate from Start Time 8:00am and what is the End Time? with 1 hour lunch time...

Thanks,

Happy Day to all,

A1= time in
B1= time out
C1= time in
D1= time out

I want to calculate the late and under time,
Office start at 9:am w/30 mins Grace period,
The break time is one hour only, please include over breaktime in calculation.
End of office hours 6:00 pm, strickly no over time

I need a formula to calculate Turn Around Time. Find below the sample data and details for your reference.

Received Date & Time: 10/29/2010 3:27:00 PM
Completed Date & Time: 11/1/2010 3:57:32 AM
Business Hours: 08:00 AM to 05:00 PM
Non Business hours: 05:00 PM to 08:00 AM
Weekdays : Monday to Friday
Weekends: Saturday & Sunday

If I calculate TAT for this time period it should show me 1 hour 33 minutes, why because business hours are closing by 5:00 PM on 10/29 so it should not calculate duration after 5:00 PM to until 08:00 AM on next day, however 10/29 is Friday so formula should calculate the duration from 10/29 Friday 3:37 PM to 10/29 5:00 PM and again it should calculate from 8:00 AM on 11/01 Monday and formula should skip Saturday & Sunday.

In this scenario I have completed the task before 8:00 AM on 11/01 so it should show duration of 1hour 33 minutes.

Please let me know if you need any more details

I have a sheet which has the start, stop and time taken for lunch breaks.

I want to calculate the total time worked such that i have the hours worked. So if i worked 7 hours and 30min then the total time would be 7.5hrs. But i am not sure how to take into account the lunch break time (see enclosed sheet).

anyone have any ideas?

I am looking for assistance in having one cell in a text format equals another cell that contains a time value in hh:mm format.

For example: Cell A1 has a time format (hh:mm) value of 04:00; which is the Start Time. I would like cell D1 to have a text format value of "04:00" (result is dependant upon what is entered in A1). I would duplicate the same formulas to reflect Stop Times in other cells.

My final result is to have another cell (F1) use the Concatenate formula to have the Start and Stop time shown in one cell as "04:00 - 12:30". The times would change based on the Time formated values entered into the Start and Stop time cells.

I have researched this in the board and found many excellent ways to do the opposite, but not convert Time format to Text format. Any assistance is greatly appreciated.

I am trying to calculate time based off a non-conventional quarter hour time system

example;
8:00 to 8:07 = 8.0 hrs
8:08 to 8:23 = 8.25 hrs
8:24 to 8:38 = 8.5 hrs
8:39 to 8:53 = 8.75 hrs
8:53 to 8:59 = 9.0 hrs

I am having trouble writing an equation that would sum the clock-in and clock-out times (2 per day) and display the total time in these quarter hours and adding an additional hour if it is >= to *:53. Any help would be great.

How do I calculate the number of batches per hour? Here's what I have so far:

Cell B5: start time: 4:15 formatted as 4:15:00 am
Cell B6: finish time: 6:15 formatted as 6:15:00 am
Cell B7: total time: 2:00 formula in cell: =TEXT(B6-B5,"h:mm")
Cell B8: total batches processed: 22 (this is entered manually)
Cell B9: batches per hour: formula in cell: =B8/TEXT(B7,"h")

as long as I have this formula in cell B9 the answer comes out correct which should be 11 per hour.
If the formula in B9 is B8/B7, the answer is 264.0, Is this because of the way excel is reading the total time or the total time is formatted as a time, not an actual number? Is this the correct way to solve the problem?
answer should be 11 per hour.

Hello,

We have a client who will pay using the 1/4, 1/2/ and 3/4 of an hour increments as follows:

From the hour mark to 6 minutes = 0 time paid
Over 7 minutes to 15 minutes = 1/4 hour 15
16 minutes to 30 minutes = 1/2 hour 30
30 minutes to 45 minutes = 3/4 hour 45
46 minutes to 60 minutes = one hour.

They work on shifts and the operation is 24 hours. Each gets 30 minutes for breaks which is not paid. Pay is biweekly and overtime is anything over 40 hours. Currently, the template we are using looks like this (sorry, I could not figure out how to paste it so you can see it in Excel layout):
WEEK 1 Sunday Monday Tuesday Wednesday Thursday Friday Saturday
5/16 5/17 5/18 5/19 5/20 5/21 5/22

Hi there

I am trying to calculate our On Time Delivery. I want this as a simple percentage of jobs. I have got this running in the following way:

Column M - Estimated Delivery dates
Column N - Actual Delivery dates
Column O - =IF(SUM(M2-N2)>0,1,0)

Then I have calculated On Time Delivery as: =SUM((SUM(O2:O252))/(COUNTA(N2:N252)))

This seems to work fine. My problem is, if we enter a date in Estimated without a corresponding Actual date, the formula for Column O fills out anyway and improves our On Time Delivery Percentage. How can I set this up so that the formula doesn't calculate if there is no data in Column N?

Any help much appreciated

Thanks,

I am trying to figure out how to write a formula to figure out production cycle time.
We will be building 8 "widgets" a day.
We will work 10 hours a day.
There is a 20 minute break at 9:20 am.
Production shuts down for lunch 30 minutes for lunch at 12:30.
Production starts at 6:00 am.
Here is what I can do.
Production cycle time = (10*60)-30/8 or 71.25 minutes
If we start at 6:00 am, the first scheduled cycle completion time = TIME(6,0,0+71.25/1440)

My problem is when I am trying to use a logical "IF' statement to account for the 20 minute break or lunch and still calculate the end of each cycle time through the day I receive a number of error messages.
This is the formula I am trying to make work. I have the cell the formula is in, formatted with a "mm,ss" format.
=(IF(D4+G1/1440>9:20,(D4+G1)/24,(D4+G1+15)/1440))
I have included an attachment to help (a picture is worth a thousand words).

Any help will be greatly appreciated.

I am trying to calculate the average Talk Time into Minutes and Seconds. Every time I have tried, I get the wrong average.

For example, if I have a total of 53 calls and the total talk time is 4:19:05, what would the average talk per call be? I tried doing everything in seconds (this would give me a total of 15545 seconds) but the total I was getting is 4:89.

What would the formula be to get the correct average time?

I have an excel worksheet that adds two other worksheets in a data
triangle. I copied it to create a new data set and used find &
replace to change the worksheet references to the new ones.

The cells still contain the result of the old formula referring to the
previous worksheets. The only way I can get the formula to return the
correct result is to edit (F2) each cell and press enter. Calc now
(F9) does nothing.

I've seen this before, but this time, I need to calculate many
thousands of cells and don't have time for this workaround.

Any ideas?

Thanks.

Hi all,

I have a dillemma here,

I have to create a schedule which incorporates lunches automatically (either half hour or 1-hour lunches, depending on the circumstances).

The schedule only has time in and time out, but I need excel to automatically deduct the lunch break depending on the circumstance:

If you worked less than 6 hours = no lunch
If you worked more than 6 hours, but less than or equal to 8 hours = 0.5 hour lunch
If you worked more than 8 hours = 1 hour lunch

I am assuming the formula for this will be really long, but I have looked online everywhere and have not found ONE formula for it. I can't put lunch breaks seperately, so all I have to work with is Time in/out.

Also, I wouldn't be able to use military time, so I don't know how excel can assume that time in is in the morning, and time out is in teh evening and/or half-day.

If someone can help it would be greatlyyyy appreciated

I am attempting to figure out how to change the formula to automatically subtract a 30 minute lunch if the total time for the day exceeds 6 hours worked.

B value Time of day punch in: 9:30 AM
C value =IF(D11="","","-")
D value Time of Day punch out: 6:00 PM
E value =IF(D11="","",IF(D11

On my calculator, if I divide 462,534.05 by 335 I get 1,380.70. Then if I times 1,380.70 by 335 I get 462,534.50. Which is what I need it to be because I need to calculate the difference of a figure not dividing equally.

On excel, if I divide 462,534.05 by 335 I get 1,380.70. Then if I times 1,380.70 by 335 I get the SAME result of 462,534.05.

I have to account for the difference of not dividing equally so there is some format or accounting function that's preset that I don't want but I have no idea how to fix it or format my excel sheet to calculate as my calculator would.

i have a worksheet with formulas in 15,000 cells; i have set the calculation to maunal so that you have to press F9 to calculate the sheet. \

sometimes, it takes 45 seconds to calc the whole sheet, other times, it takes 5 minutes. how do i clear the cache, or what do i have to do so that it calcs 45 seconds each time.

i don't want the application to think, it would be better if those 15,000 cells can be returned in a fraction-of-a-second. any ideas/tips? thanks.

Hello,

I have two columns of data: column A contains the date and time in the form dd/mm/yyyy. Column B contains a number value. All the times are in order, so column A looks like:

01/01/2007
02/01/2007
03/01/2007

I have data from 2007 to 2010. I need to calculate an average daily value (in column B) for each month, and display it in column C. So, for January, I need to calculate the average of 31 days, February, 28 days, etc.

Is there a function I can use to do this? I've been trying the AVERAGEIF formula but can't get it to work. Any ideas would be much appreciated!

Many thanks,
Caitlin

I've been poking around trying to figure this out but can't. The time of 9 hours, 15 minutes is being returned from a calculation but I want the cell to display the 9.25 hours instead. This seems like something simple on the surface, but apparently it's not. Any help would be appreciated!

Hi,
I made a simple worksheet that we have been manually entering the time for employees, but there are too many errors (even with simple math). Can someone help me convert the time of ex: written 8-4:30 or 10-3 (meaning 8:00am to 4:30pm) where you have the total weekly hours? Right now I have a column for overtime. Is there a way to automatically calculate the over time also? The work day is 8-4:30 with a half hour lunch (lunch is not calculated into the hours, so you minus a half hour). 8-4:30 equals 8 hours. So, if a person works 8am to 6:30pm, how can I set it up where in the first row of time, I will type in 8-6:30pm. In the totals column to the far right, it will display 8 hours. In the (O.T.) column, it will display 2 hours.

This way, when I call in my payroll, I will have the total "regular" hours in one row and underneath, I will have the total overtime hours.

Or... does anyone have a better solution to keeping track of their hours?

Thanks!
Marty

I'm trying to use conditional formatting to highlight phone calls that came in between certain hours.

The call times are in the custom format h:mm, although it could easily be changed to an Excel time format. I'm using Excel 2002. I want the cell to have a different fill color if it falls within particular time frames.

Example: If the call came in between 22:00 and 23:59 color is light green.
If the call came in between 23:59 and 08:00 the color is yellow.

How would I create a system where an excel file is updated in real time with new values? I have a program which logs data, and I want to have excel open, plotting the data in real time. Is this possible?

Sorry for the question. Normally I find answers to my excel questions by going through the help tab or by searching on Google. However, I don't even know what question to ask on this one!?!

Basically I have created a spreadsheet with several columns, but I have one column that lists the shirt size (YS, YM, YL, AS, AM, AL, XL, 2X, 3X) of each person. Is there a formula that I can create that will tabulate the number of sizes (i.e. AS=2, AM=7, etc.)?

In previous years I made a column for each size, and simply placed a "1" in the correct column, and had excel just add the 1's from each column. However, that takes more time and space. I was hoping to streamline it this time around.

Thanks for taking the time to read this post. Any help would be appreciated! Thanks, doug
