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?

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 / Frame Fps Formula (base 75)

Jan 18, 2010

I have a formula that calculates only seconds and frames. The frame rate is 75 fps (0-74).

e.g., 49.50 is 49 seconds 50 frames. It will not parse Minutes.Seconds.Frames, e.g., 1.49.50 is 1 minute 49 seconds 50 frames.

What my existing formula does is converts the number to all frames then converts the answer back to seconds and frames.

I need this formula to include minutes in its calculation.

A copy of the spreadsheet is here: ...

Number Of Days Worked Over A Time Frame

Aug 11, 2009

I need to be able to calculate the actual number of days worked for an employee over a specific date range. I have a data sheet containing employee, transactions, and date of transaction (date only, does not include time). The actual number of days worked may fluctuate due to time off or holidays, so I need to be able to calculate this individually by employee. For example, with columns Employee, Transaction, & Transaction Date:

123 ABC 07/01/2009
123 ABC 07/02/2009
123 DEF 07/02/2009
123 GHI 07/02/2009
123 ABC 07/03/2009
123 ABC 07/07/2009
123 DEF 07/07/2009
123 ABC 07/08/2009
123 ABC 07/09/2009
etc....

Should return 4 work days for employee 123 over the date range 07/01/2009-07/07/2009

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.

Count Within Time-Frame Accounting For Sick Days

Apr 3, 2008

Im trying to count people working during times of the day. They work shifts from 8am to 9pm. I need to know at each 30 minute interval of the day how many are working. IE at 12:00 or say 13:30 I need to know how many are working. I also need to be able to account for people that are sick. IE If a person works during the day I wouldnt count them as sick at night.

Im data is set up like
Column A agent name
Column B agents start time
Column C agents end time
Column D holds two variables either sick or support.

I have found a thread that counts the people working but doesnt account for the sick or support variables. I didnt link that thread as I thought it went against the rule "STATE WHAT YOU WANT TO DO, NOT WHAT YOU THINK YOU NEED TO ACHIEVE IT "

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))

Adding And Subtracting Time

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 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.

Summarizing Times For Specific Items Within Specific Time-frame

Mar 26, 2014

I got Excel for Mac 2011 installed. I have a table called 'Raw" that holds data from the beginning until the end of 2013 (in total ~7000 rows). I have columns for Category, Start and End time, and time period in Hours, Minutes, and Seconds:

Code:

2013/01/01 01:15:00
0:15:00
15:00
900

[Code] ...........

I'm trying to get an overview of how much time I've spent in January on Transportation. I would need to look at the Category entries for Transportation, then only use the ones which have the Start set to 2013/01, and then take the Hours/Minutes/Seconds, and summarise it in a new table called 'Data':

Code:

B
C
D

Month

Add This Number To The Start Time, Factor In Break Minutes And Get To The Projected Completion Time

Mar 3, 2009

I am trying to provide a tool for department leaders to monitor productivity for order processing in their departments. The variables I have are: Number of orders(variable), number of pickers (variable), start time(variable). Then, I know each order takes 1 picker 4 minutes to pick on average, and there are 45 minutes worth of breaks during the picking process. So after entering the variables I used =(((C3*4)/60)/D3) to come up with the time needed to process the orders. What I can't get to is how to add this number to the start time, factor in break minutes and get to the projected completion time. I have Excel 2003 at work. Clearly I need to take a class!
