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))

Need to calculate the mean hours by the day of the week. We only want to know the mean if it occured after a certain time and if it was on the same date then that would be totalled for that particular week day. I have included a small sample of the file I am working on.

I'm trying to calculate the available man hours I have for my shift/team. I have got the basic formula to deduct the time, and lost time for breaks ok, but when the shift end time crosses midnight the formula returns a "value" error message. i.e. start time = 18:00. End time = 24:00 breaks = 15 mins gives me a formula like this =TEXT(O17-N17-P17,"h:mm") and a result of 5:45
How I can make this formula work so it can calculate the variance even though the shift ends at 02:00am the following morning?

I’m working on a timesheet and I need to separate the hours worked that are before 6 am from all the others. For example if someone works 1:00 am to 8:00 am I need a cell to populated with 5 representing the hours worked before 6 am. The formula below works fine except when the start time is 12:00 am. I am also having trouble if the start time is before midnight like in a 11pm to 5 am shift.
=(IF(AND(S3<=$AG$97,S3>=$AG$73),(($AG$97-S3))*24,0))
S3 is the start time
AG97 is 6:00 am
AG73 is 12:00 am

I Have 20:00-04:00 as text in a cell, what i need is to take the 04:00 and show only if its after 00:00 and before 07:00 and show it as time value. This is where I'm up to so far but i don't know how to ask it for > 00:00 and < 07:00.

I am creating a timesheet using excel 2003 users enter their shift start/finish time and a break start/finish time. Emplyee's can work night shifts (ie across midnight).
There are penalty rates which apply at different times. I need to be able to work out the amount of worked time that fits into a certain time period. eg. 10pm-7.30am, 7.30am-10pm.
I have a solution based on A clever formula from Daniel Maher that will calculate time within a period. But it doesn't work when the shift goes over two days.
I have attached a spreadsheet to help show the problem .......

I have time in the column C and its Description in column D. i want to calculate total number of hours from "9:26:00 PM" which is in C16 to "3:23:14 PM" which is in C1. from this total hours i want to deduct the time that agent was not available. for eg an Agent is not available from "3:23:14 PM" To "3:23:53 PM" then again from "3:26:57 PM" to "3:27:13 PM" Then again from "3:42:35 PM" to "3:44:10 PM" and so on.......thus i can find out the productivity time lost from the total time an agent was logged in. I have attached the Sheet so that it will be simpler to understand.

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?

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.

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?

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?

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? ....

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?

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 ....

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.

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.

My challenge is discovering the difference in time between two rows of data that is imported with milliseconds in the time slot. In my example below I would like to see how I can subtract the time listed in line 4 from line 3 (11:18:59.566 - 11:18:59.550). When I try now I get either 1.85185E-07 or 00:00.0 or 0.000000 depending how the cell is formatted.
2012 02 17 11:18:59.050|081,999999999999~999999999999
2012 02 17 11:18:59.550|082,MCTO05222CZ0~999999999999
2012 02 17 11:18:59.566|082,1
2012 02 17 11:19:00.144|083,MCTO05246CK0~999999999999

I am trying to subtract 12 business hours from a date/time stamp. It has to be during working hours however which are 8AM - 5PM, Monday-Friday.
For example if my value is 6/23/2008 9AM
Subtracting 12 business hours would give me 6/19/2008 3PM.

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

I've tried to work around an issue so many different ways that I could easily ask a dozen questions about why something I tried couldn't work, but if I could just fix the original issue I wouldn't need the workarounds.
I think I need to query data using this format:
SELECT [Fields]
FROM [DataSource] WHERE
(
((S.LabelDate>={d '2008-08-19'}) And (S.LabelTime>'0500')) And

I am trying to use conditional formatting for employee's shift hours. If they work between 22:00 to midnight they get 1.25 penalty rates. And if they work between Midnight to 7am they get 1.50 penalty.
I am basically trying to highlight cells a particular colour if an end time finishes between specific times as per below. This is so Managers can clearly see who is working at what penalties however I am having trouble as it runs through midnight.
This is the conditions I am after.
Between 22:15 to 00:00 = Highlighted Red
Between 00:15 to 6:45 = Highlighted Yellow
Between 7:00 to 22:00 = no formatting required
As per attached example, I can only get between 22:15 to 23:45 to work. Not sure if I am on the right track or completely off the mark!

23:00Â ->Â 1:00Â =Â 1:00
01:15Â ->Â 4:15Â =Â 3:00Â

I have various start times for employees.
I need to find out the total movement in start times per week for the employees.
I have used MIN and MAX to find the earliest and latest start times, and then a subtraction to find the difference.
This works brilliantly until my employees who start around midnight.
If they have started before and after midnight, it takes midnight as the earliest time and 23:00 as the latest, giving a difference of 23 hours instead of 1 hour.
i.e.
Start Times
23:00, 23:15, 00:15, 00:30
Range of Movement
00:30 - 23:00 = 01:30
I've tried, =$B$9+($C$4>$B$9)-$C$4 but this does not work when the MIN reads 00:00.

Simplifying the following formula:
'=((F17-F17)*D17)+((F17-F16)*D16)+((F17-F15)*D15)+((F17-F14)*D14)+((F17-F13)*D13)+((F17-F12)*D12)
Its basically the sum product of column F time column D...however, all the F values are first subtracted from the last F value; Obviously I could just have an extra column to calculate all the new "F" values the issue with that is that I want to be able to drag down the formula and so the value F17 changes for each last value in column F...

I have two Ranges, which I view as Arrays or Matrices, I want to subtract the two (which do not overlap or union in any way) to get a new third range of the differene. This new range should be the same size, and can be considered a difference of each cell in the range. Note both ranges are already identical in size.
Any help solving this, searched up and down for hours.
Note; Im trying to avoid looping, as this might become incredibly inefficient if the ranges grow to big, looking for alternative that is faster, someone said maybe excel.evaluate
