Subtracting Time/date Using NOW Function

Oct 6, 2009

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 ....

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?

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.

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?

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?

Referencing Then Subtracting A Date From Another Workbook From Today Date

Jun 6, 2014

I am trying to take the year from today's date then subtract away a date from a referenced date in a separate workbook. Then I want to put this result into an IF statement. For example if the result is between the number 1 and 4, display 1, if the result is between 5 and 9, display 2, etc. Right now, I'm simply trying to reference the separate workbook for the date and subtract that from today's date, but I'm stuck because I only get the date's serial number back.

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.

Format Now Function For Time & Date

May 10, 2007

I have two worksheets which talk together and one of them gives a time stamp using some VBA code

=format(Now(),"dd/mm/yyyy AM/PM"

in the other spreadsheet I have the Now() function which has been working fine. However, when another user went into the spreadsheet went in it, my calculations between the two dates now error. I am presuming its because of the now function not having some formatting defined so is there anyway of changing this value? The cells-formatting will not obviously work as excel is getting confused between the two time types even though the format looks fine. To help the calculation that is messing up is

=IF($L7="","N",IF(DATEDIF($L7,$J$1,"d")>10,"N","Y"))

whereby L7 is the imported timestamp and J1 is now(). The calculation is to show which accounts become inactive after 10 days.

After reading up on the internet I know that to get round the problem I have to make sure that everyone is using the same regional settings. But I just have a couple of questions:-

1. I can understand the date calculation not working on the other persons machine, but when I went back to look at it I was getting the same error. Even though the file is shared, how come my settings didnt 'overwrite' and how come i was affected?

2. Is there a way to make the code work regardless of who opens it in whatever region? Im not sure if there is a fundamental problem but I cant rely on everyone having the same settings because I know that this will cause problems in the longterm.

3. Using the formuale Now(), is there no way of forcing that to a uk date format to stop the errors?

Completing IF Function With Date And Time As Inputs?

Jan 16, 2014

Using the attached doc, and its legend tab, I need the following columns corrected as I am seriously tripping up on formats vs inputs for outputs.

1.) Column "N's" result based on the duration output of the preceding column "M" is:

<=4 = 40
5 = 30
6 = 20
>=7 = 10

2.) Column "Q's" result based on the duration output of the preceding column "P" is:

<=18 == 40
>=19<=24 == 30
>=25<=48 == 20
>=49 == 10

The legend tab shows the info as well.

Subtracting 1 Day From Date Calculation With Multiple Cells?

Dec 10, 2013

Here is what I have:

A B C D
Date ReceivedApproved DateDenied DateTurn Time
1/1/14 1/13/14 9

Turntime is calculated with this formula:
=IF(A4<>"",IF(COUNT(B3,C3),NETWORKDAYS(A3,IF(B3<>"",B3,C3)),""),"")

What I need is to not count the first day it is received in the calculation for the Turn Time. So in this instance I need the Turn Time to say 8 instead of 9. If I just subtract a 1 then I get an error if the Approved Date or the Denied Date are not filled in yet.

Date/Time Formula: Pick Up A Date With Time Entry On A Worksheet And Place It Into A TextBox On A UserForm

Jun 17, 2006

I am attempting to pick up a date with time entry on a worksheet and place it into a TextBox on a UserForm. Format on the sheet is mm/dd/yyyy h:mm AM/PM. The UserForm is placing the value as mm/dd/yyyy 12:00 AM. here is the

Private Sub UserForm_Initialize()
If Not Range("dDate").Value = "" Then
TextBox2.Value = Range("dDate").Value
TextBox2.Text = Format(DateValue(TextBox2.Text), "mm/dd/yy h:mm AM/PM")
Else
TextBox2.Value = ""
TextBox2.SetFocus
End If
End Sub


"dDate" is the named range where the date is sitting. The format is also set on the TextBox2 exit event. Can anyone see why only the date portion is being transfered with the default 12:00 AM for no time component of the value?

Convert Imported Date / Time Data To Date / Time Format?

Jan 2, 2013

I have loaded a .csv file in which the first column contains date/times, e.g. 01/12/2012 00:00. How do I now tell Excel (2010) that this is in fact a date/time format? If I select one or more of the cells, click on the Number dialog box launcher and try to pick a suitable format tghe cells resolutely refuse to budge from being text (i.e. left-justified, still allows me to edit the 'seconds' component to a number > 60). Also which data type should I be using? The only one that appears to have a full date/time format listed is Custom (not Date or Time).

DATE Function & IF Function (return A TRUE Or FALSE Based On A Date In A Cell)

Dec 8, 2009

I am trying to return a TRUE or FALSE based on a date in a cell.

for example:

if cell A1 = 07/11/2009

I want A2 to show TRUE or FALSE if A1 is 14 days or more behind todays date.

I have tried stuff like:

=IF(A1=TODAY()-14,"True","False")

but it just always says false. EDIT: I have just noticed that if I change the date in A1 to exactly 14 days behind todays, it returns TRUE. So, it does work. Do I need to add a GREATER THAN in there?
