# Subtracting Time (in Numbers) To Decimal

Oct 21, 2009

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.

## 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 Subtracting

Jan 30, 2007

I have three cells... A1= entry time & H1 exit time...both are formated as such Custom #0":"00 so i don't have to enter the colon with every entry and exit time... my issue is that i want the third cell to count the minutes in cell A1 & H1...

## 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))

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 A Field That Has Time

Jan 21, 2010

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? ....

## Subtracting Until Zero From A Series Of Numbers

Jul 3, 2014

I'm trying to program a spreadsheet for staff attendance at a school. In the spreadsheet the staff member has personal days, sick time, and sick time in the bank (sick time rolled over from last year). When they use sick time, it needs to come out of the bank first, until it reaches zero, then it should move on to the sick time accumulated for this year.

Staff attendance WIP.xlsx

On the left side is the staff name, sick time, personal days, and bank. Then are the school days for July (if a staff member uses sick time/personal day it is placed under the date it was used). On the far right is the total remaining amount that the staff member has left.

The formula I have for cell AF4 is: =MAX(0,G4-SUM(H4:AC4)) so that the cell will not go below zero.

The formula I have for cell AG4 is: =E4-(COUNTIF(H4:AC4,"P")+(COUNTIF(H4:AC4,"HP")/2)) So that when P for personal day is entered, it will take a whole day, and when HP is entered a half a personal day is subtracted.

I need to figure out a formula for cell AD4. I've tried a couple of formulas I've seen on other posts, but they weren't for a series of numbers like this. And when I put them into this particular spreadsheet, it would subtract the bank until zero, move on to the 'sick time' cell and subtract the SUM of all the days sick rather than subtracting what was left when the 'Bank' reached zero.

## Losing A Minute When Subtracting Time?

Jan 6, 2014

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?

## 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 ....

## 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.

## Excel 2010 :: Subtracting Time In Milliseconds?

Mar 2, 2012

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.

## Calculate Time Difference In Decimal Time

Aug 16, 2008

I've got a time difference from 8:00AM - 12:30PM as 4.30 I'm trying to get the minutes, .30, converted into a 6 minute increment, .5. Is it possible to do this and if so how would it be done? Below is a chart of how the time is converted from 6 minutes increments into decimal form.

6 = 0.1 36 = 0.6
12 = 0.2 42 = 0.7
18 = 0.3 48 = 0.8
24 = 0.4 54 = 0.9
30 = 0.5 60 = 1.0

## Convert Number To Time & Decimal Time

Oct 8, 2007

I need to separate a list of times from a telecommunications bill. I have 170,000 line of data.

The Times are represented as below.

eg

46 46 Sec
59 59 Sec
100 1 Min
159 1 min 59 sec
200 2 mins
502 5 mins 2 sec

3456 34 min 56 sec.

How do I separate them to a decimalized per min value.

## Converting Decimal Numbers To Text With Dot Numbers

May 27, 2006

we work with both Lotus 123 and Excel 2003. Lotus will be gone next year, but for now, the official mean to publish our reports is Lotus. With my work, I copy/paste a Lotus page to Excel. I use the following macro to convert Lotus format numbers (which Excel considers as text) to real numbers:

Sub ForceToNumber()
Dim wSheet As Worksheet
For Each wSheet In Worksheets
With wSheet
. Range("IV65536") = vbNullString
.Range("IV65536").Copy
End With
Next wSheet
End Sub

Source : http://www.ozgrid.com/forum/showthre...087#post184087. The problem is that I need to send back this data in Lotus. Excel considers decimal numbers with a coma as real numbers and numbers with a dot as a text. This previous macro fixes that. However, Lotus works the other way. Only numbers with a dot are considered real numbers. So I would need to find a way to code a macro that converts any numbers in the Excel sheet to a number with a dot. It's a bit like doing the opposite operation.

## Decimal Time To Standard Time

Jan 6, 2009

How do you convert decimal time to standard time?

....Hrs

I know 1.5 is 1:30 but I don't know the formula.

## List Only Whole Numbers From Decimal Numbers

May 23, 2009

From a list of numbers I would like to delete values that have cents so only those transactions with a .00 amount are displayed

For example

34.95
21.88
21.00
56.00
45.77

Only those valaues ending in .00 will list. I tried filtering but I think there most be a function(s) string that might work or at least filter out the values with cents

## Express Time As A Decimal And Add

Jun 8, 2009

I'm trying to make a shift schedule template, and it's all done except that i cant sum the hours the way I think i should be able to.

I've attached the file for reference.

I've added in some hours for myself as an example. I have 47.5 hours in the week. I've got 3 Rows, In Out and Hours. I've formatted the In and Out the way i want them, but I would like the Hours row formatted as a decimal, so that 7 hours 30 minutes would show up as 7.5.

I'm also having trouble with the totals column at the end. Although D8:J8 total 47.5 hours, it's adding them as 23:30.

## Time Of Day As Negative Decimal

Feb 6, 2012

Data from a SQL database represents time of day as a string of x's when imported into Excel. With CLEAN, I found that noon is -0.5.

This means that the calculation being used for noon is (24 * -0.5), or -12, meaning "go to the end of the 24 hour day, then go back half a day to noon." Similar calculations work other times of day.

Time entries that start in one day and end in the next are not allowed, so there is no problem with a change in day,

How can I convert this to the AM/PM time that my users need?

## Convert Time To Decimal

Jun 12, 2009

I am trying to convert time (formated as hh:mm) to a number with 2 decimal places.

Will then multiply this by an hourly wage to get total \$ paid.

## Delete Decimal Numbers Only?

Dec 14, 2008

Is there a way to delete only numbers ending in a decimal from a column of numbers? I have a column of numbers but only the non decimals are relevant to the next equation.

## Counting Decimal Numbers

Oct 25, 2006

I am trying to find a way of counting decimal numbers if, say, they begin with 3.

For example, I might have 3.33, 4.1, 3.0, 5.65, 3.8, 3.7, 3.33, etc.

I want to count anything that begins with 3 (3.33, 3.0, etc). Using the data above the answer would be 5 ...5 numbers that begin with a 3.

If this possible?

There doesn't appear to be the facility with Countif. I don't want to truncate the data (the spreadsheet already is quite extensive). I have tried using =SUMPRODUCT((Y\$2:Y\$170 >=3)*(Y\$2:Y\$170<=3.9)) but this will return an answer only when there is a complete set of data within cells within the range.
