I am trying to determine the total hours of downtime accumulated when there are 2 or more machines down during the same time period. To do this, I need to be able to determine if at any point there are 2 or more pieces of equipment down at the same time, and if this is true, how many hours were overlapped. The attached spreadsheet shows how the data is presented.

Any way to calculate the total hours staff work based on the mininum time of the first transaction to the maximum time of the transactions. I used a DMIN and DMAX function to get those times per employee. The issue is then the time goes over from one day to the next, such as from 11 PM to 4 AM the next day. As you can see in the data below,the fourth record shows the minimum time as 12 AM and the max as 11 PM with total time worked as 23 hours. In this example, the total hours worked should be five hours.

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?

Is there a method to calculate the total number of hours in excel. In my attached file, the excel treat the 24 hours as time and recalculate from 0 hour.

Having trouble adding a column of minutes and converting the total into hours and minutes. Say Cell A1 through Cell A18 each have 12 minutes in each cell. I want cell A19 to tell me how many hours and minutes of total time that have elapsed. I have tried hh:mm, [hh]:mm, but nothing works.

What I need is a formular/vba code that can divide hours into different time ranges. The picture below shows an explanation.

In example 3 there time range analyzed goes from saturday till monday. Here Sunday should get 24 hours and the time range 23-08 for weekdays is at this point 00-08.

I've tried everything I could imagine to get this one working,

I have call data in date/time 06/07/08 2:00 PM custom format for a 2 month period. I have my regular opening times eg Monday 9-3, Tuesday 10-4. For each call I want to know if it was made during opening times or not.

I have a column of tasks that take a certain amount of time to complete formated as h:mm:ss. I want to total the column and convert the total to days, hours and minutes. Is that posible and if so how do I configure a formula and format the cell? example:

I am trying to figure out a formula in L3 which is the calculation of overlap of region1 and region2. The top row is the number of days. What formula can I use to calculate the percent overlap? The numbers in column L show the expected result.

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.

Is it possible to calculate hours if both the start and end time are in the same cell. Unfortunatly the developers of our scheduling program developed it so when you export the schedule to excel it shows Greg in A1 and 3:00pm-9:00pm in A2. I would like to have excel calculate the 6 hours so I can use it to auto generate another spread sheet I am making.

i have a timesheet that we are trying to use. the problem is the column that says shift diff. if an employee works after 6:30pm for 1and 1/2hr, he is entitled to shift hours. shift hours is between 6m and 8am.

As long as he works after 6.30pm but works for at least one and a half hour, he will get the shift.

if work, 9am to 7:30pm, and have break between 2-3pm, should have 1.5hrs shift and 9.5hrs total if work, 7:45pm-9:45pm, and have break between 8:30-9pm, total hrs work is 1.5 and shift hrs s/b 1.5hrs if work 3pm to 12am and have break between 7-8pm, total hrs work is 8 and shift hrs s/b 5hrs

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 am trying to build a spreadsheet to calculate how many hours have elapsed between to entries; start time (H10) e.g. 9:15 AM and end time (I10) e.g. 12:15 PM. The formula that I am using in the calculation cell field (J10) is (I10-H10+(I10<H10))*24. This formula works great till I wish to include in an IF statement. What I would like is if the total hours calculated with the formula (I10-H10+(I10<H10))*24 is less than 4, return 4 (hours) otherwise the value. As well if there is no start time nor end time entered then return zero.

I am trying to find a way to calculate the number of hours between date/times found in separate rows. The attached data set will help to envision what I am talking about.

For each couple of rows, I need to find a way to calculate the number of hours elapsed from row 1 to row 2. In the first example, to calculate the number of hours between 12/2/2009 8:56:51 and 12/4/2009 6:35:27.

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

Based on above data if The Column heading is 1 then it needs to go to the below data and multiply by that value and at the end should give me the total for the person. note that the total time is captured in a different sheet.

Label 1 = Time when form initialized or opened Label 2 = Running Time (Live Time) Label 3 = Total Time (Label 2 - Label 1)

Now what I need is since Label 2 is live time which shows the running time, Label 3 displays the total time spent. I want to display total time as running time.

e.g. Label 1 = 13:01:00 Label 2 = 13:05:10 (running time/live time) which will keep ticking Label 3 = 00:04:10 (I want even this as running time which keep running when label 2 is running)

In the example above, E2 calculates the totals between 12/8 and 12/9 giving me 15:00. What I want the formula to exract is the total from Col D the total from 12/9 to the previous 24hrs.

12/8 has 2 entries, and 12/9 has 3 entries. The total I want to extract in 24 hours, NOT 1 day, is 14. What formula can I use that will calculate the totals in 24 hrs.

I can calculate total hours when a user enters a start date/time and a finish date/time. The kick is I only want to include hours from 2:00 PM to 12:00 AM (10 hour period). So assuming all the start and end times will be in this range, how can i calculate work hours over multiple days? For example: Start date/time = 2/26/13 2:30 PM and end date/time = 2/28/13 10:30 PM. I want my calculated hours to show 28 hours.

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

I am staring at this excel spreadsheet blankly ... I am at a loss as to how to accomplish the detailed analasys but simple math this spreadsheet reequires.

The data consists of three columns pasted from a report that is exported as a .csv:

B Code C Start Time D End Time

The following analyses must be made on each row:

1. determine if the start time falls within the scheduled shift
