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?

How do I work out the cost per call in Excel?

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?

Macro That Runs Every Minute When System Clock Changes Minute?

Sep 13, 2013

create a Macro that runs when system clock changes minute and then at every change of minute of system clock.

For example, if I give the execute command to start the macro at 09:14:45 (HH:MM:SS), then its first run should be only at 09:15:00, then next run at 09:16:00 so on...

I already have a Macro that runs every minute from initial run time, using

Code:
Application.OnTime Now + TimeValue("00:01:00"), "MyMacro"

but it seems to be unreliable, because in case I open another sheet that takes lets say 20 seconds to open, the next macro run is delayed by 20 seconds.

Round A Time Entry To The Next 30 Minute Increment

Feb 2, 2006

I have a worksheet that I enter time values into individual cells:

A1 = 6:00
B1 = 12:00
C1 = 12:45
D1 = 17:15

When I enter these values, I would like some of the values to round to the
next higher "30 minute increment" such as Cell C1 should become 13:00.

I would also like some of the values to round back to the next lower "30
minute increment" such as Cell D1 should become 17:00.

Time Clock Six Minute Rounding Formula

Apr 27, 2007

I am trying to figure out the written formula for needing this answer:

For a time clock with 6 minute rounding.

If I type in 8:20 as the arrival time, I need it to round to 8:18, so that the final time will be in tenths.

Here is the rounding:

Actual Rounded Minutes in Time Clock
:57, :58, :59, :00, :01, :02
:03, :04, :05, :06, :07, :08
:09, :10, :11, :12, :13, :14
:15, :16, :17, :18, :19, :20
:21, :22, :23, :24, :25, :26
:27, :28, :29, :30, :31, :32
:33, :34, :35, :36, :37, :38
:39, :40, :41, :42, :43, :44
:45, :46, :47, :48, :49, :50
:51, :52, :53, :54, :55, :56

Anything in the same line will round to the bolded time.

Example: I arrive to work at 8:09 and go to lunch at 11:59, it will round to 8:12 and 12:00, making my time worked 3:48 or 3.80. Then I get back from lunch at 12:59 and leave at 17:14, which will round to 13:00 and 17:12, making my time worked 4:12 or 4.2 for the 2nd 1/2 of the day and 8:00 or 8.0 hours for the day.

Time In----------Time Out----------Total Time----------Decimal Time----------Total Hours
...8:12.................12:00..................3:48......................3.80
..13:00................17:12..................4:12......................4.20..........................8.00

The problem is I want to write the actual time and not have to round everything myself and yet I need the decimal time to match what my time clock actually calculates from.

My current formula for the decimal shown above as 3.80 is this: =(HOUR(F7)*60+MINUTE(F7))/60
My current formula for the total time for the day (regular hours) is this: =IF((((E7-D7)+(I7-H7))*24)>8,8,((E7-D7)+(I7-H7))*24)
My current formula for overtime is this: =IF(((E7-D7)+(I7-H7))*24>8,((E7-D7)+(I7-H7))*24-8,0)

This is not a time clock, it is my personal copy of what my time for the week was/is, so that I can compare it to the actual time card that I have to sign off on.

Convert Hour / Minute To Another Predefined Time Mode

Feb 27, 2009

Here is a traditional Indian time calculation

(1 day) 24 Hr = 60 N
1 N = 60 V = 24 Minutes

How to formulate this in excel 2003.

If A1= HH (hour), B1=mm (minutes) - Inputs
A2 should show NN : B2 should show VV - Result

And Viceversa.

If A1= NN (hour), B1=VV (minutes) - Inputs
A2 should show hh : B2 should show mm - Result

hh - hours, mm - minutes, NN - Nazhigai, VV - Vinadi - all are numbers

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

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?

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.
