Changing Elapsed Time Into Time As Portion Of An Hour

Sep 11, 2013

In A1 I have 35 min elapsed time and need to change it to time as a portion of an hour. It reads the 35 min as TIME, therefore I am currently using

=IF(A1>=0.5,A1-0.5,A1)*24. Output is .58, which is perfect.

(output column formatted as a number)

Likewise 3:28 becomes 3.47.

Changing Date/time To Run A 12 Hour Production Schedule, And Not 24 Hour

Sep 4, 2006

I have created a daily schedule which has a number of factory variables taken into consideration which determine the date and time a particular product should, barring any mechanical problems, come off the machine. (see attached spreadsheet).

The date at the top will be editable by me only so that when I update the production quantities, the date/time off column automatically re-adjusts to the remaining quantities.

The formulas are a little long winded, but I have left them that way whilst I try and develop it. I should be able to figure out how to condense them later.

My problem is that the date/time off on the right works excellent, but over a 24 hr period.

Ordinarily, we work a 12 hour day (6am to 6pm) with overlapping shifts to cover breaks, and 20 mins warm up at the start of the day for the machine, thus maximising a 12 hour day.

Of course if demand exceeds the allotted time we put on overtime.

Is it possible to specify that normal days are only 12 hours so that if a product exceeds 6pm, it flows into the next day with the balance starting at 6:20am?

And, if the production for the week exceeds the time could I stipulate particular days which we deem are suitable for overtime? Ie, we decide Wednesday is a 14 hour day and not 12.

I had toyed with the idea of creating a 365 day table/calendar, on another worksheet which would have its individual allocated hours in an adjacent column and somehow link them to the date/time off, perhaps by way of a VLOOKUP, but I have been chasing my tail trying to figure out how to implement it.

Time Stamp Macro Tell Total Elapsed Time From When I Started To When I Finished

May 22, 2009

I am not sure that I can do this, but here is what I would like to do. I have a worksheet that I initial when I start a job in on cell and then when I finish in another cell. What I's like is to have a macro running in the back ground that will tell me the total elapsed time from when I started to when I finished.

Need Start Time - Have End Time And Elapsed

May 8, 2014

How to find the elapsed time between two times, but I need the start time in this instance.

Attached is my spreadsheet for a callcenter in which has exported data showing what time the data is exported and how long someone has been their state if they are out of adherence. I have selected fields explaining what I am wanting where on the spreadsheet.

I am wanting to subtract the elapsed time in MM:SS from the End Time which is in HH:MM AM/PM (Imported as text). I do not mind moving these to separate cells to the left to format them correctly, I want to be able to right click in A1, paste, and the rest trickle.

I am having difficulties subtracting the time to get the start time.

I have a list of FLIGHT departure times that are listed in MIL TIME, however, there is no : in the format. Its just 4 or 3 digit numbers. I need to convert these to time in 12-hour clock. If I go to FORMAT/CELL/TIME and select 1:30pm it simply makes the time ZERO!

Time W/in Each Hour Of Day Btwn A Time Range

Dec 20, 2007

I need a formula to calculate the time (in hours/fractions of an hour) that is "covered" for each hour of the day between a range of times. In other words, I have a "START TIME" and an "END TIME" and for each hour of the 24-hour clock, I want to know how much time this range covers.

For example, if my start time is 3:30am and my end time is 5:15am, for the 3am hour, the formula would return 0.5 hours, for the 4am hour it would return 1.0 hours, for the 5am hour it would return 0.25 hours, and for all other hours it would return 0.0 hours. The range of START TIME and END TIME can be up to 24 hours (but not more), but the tricky part is that the START TIME can be on the day BEFORE the END TIME (e.g., START TIME of 10:35pm and END TIME of 5:45pm the next day).

Time Sheet :: 12 Hour Time Format With AM/PM

Mar 13, 2008

I found a formula for calculating time in the HH:MM AM/PM

=IF(B1<A1,B1+1,B1)-A1

This formula was to give me total hours in the cell for which it is entered, and cell format for the formula was in military format.

I cannot find this post. The formula worked in OpenOffice Calc program, but when it came to converting to excel, I came up with #value!

I want to enter the time in 12 hour format and using am/pm to designate. I am making it for someone to make work schedules with and they do not know military time.

Determining Elapsed Time

Aug 22, 2014

I have a document in which I am trying to determine the length of time between a start date & time and a finish date & time. The format of the time/date cells is

mm/dd/yy hh:mm:ss

Basically, I am just subtracting the first cell from the second. This works fine as long as both dates are in the same day, such as

START FINISH ELAPSED
08/20/14 23:42:22 08/20/14 23:43:59 0:01:37

However, if I have a situation such as

START FINISH
08/18/14 23:00:15 08/19/14 0:03:22

the ELAPSED cell fills with ######## with a tooltip stating that "dates and times that are negative or too large display as ######." The actual result in this example should be 1:03:07.

How do I get consistency amongst my resulting formulas?

Formula For Elapsed Time

Feb 22, 2008

I am trying to determine the amount of off duty time from the last stop time to the next start time. The object is to reset another column of hours (not shown here) to 60 hours only if there has been 34 hours of off duty time prior to the next start time.. I have posted this problem previously but did not explain very well I need to accomplish. The start and end times ( E & F) are formatted as hh:mm AM/PM and the Work time and the other columns are formatted as [hh]:mm. Where my formula fall short is when there are blank days indicating weekends or days off ...

Elapsed Time Display

Feb 26, 2007

I am trying to find some simple code that will display elapsed time starting from execution of a macro to a certain point where a message box is displayed at which time the elapsed time should pause awaiting user interaction. Once the user has responded to the message box prompt the timer should continue on from its paused state ceasing at the end of the macro. I would also like the displayed box showing the timer to remain visible displaying minutes and seconds and continuously incrementing even though screen updating is turned off within the macro. (The macro switches sheets a number of times) and the elapsed time box needs to positioned at bottom left of screen.

Sum Of Elapsed Time Involving Comma

Aug 12, 2014

I have been currently working with Data in which involves time over 24 hours and I am trying to find the sum of these numbers.

An example would be the following :

4,889:38:33 +4,711:28:37 + 4,851:11:26 .

Of course, I have removed the comma and changed format, this did correct the issue. However, any way to find the sum with the comma still involved.

Excel - Elapsed Time In Cell

Feb 20, 2012

I would like to develop code that does the following:

- I first manually move to a cell
- Press a key combination (CTRL+T for example)
- Press the same key combination, the elapsed time from the first press to the last press is entered into that cell in seconds.

It would be nice if the cell showed the time incrementing live, but that is not required.

Activate Message Box After Time Elapsed

Feb 26, 2012

I have a worksheet with checkboxes in each cell in A11:A110 as well as O11:O110. When a checked, the current time appears in the corresponding cell, using this code for example, A11 :

Private Sub CheckBox1_Click()
*
*** Range("A11").Select
*** ActiveCell.FormulaR1C1 = "=NOW()"
*** Range("A11").Select
*** Selection.Copy
*** Selection.PasteSpecial Paste:=xlValues, Operation:=xlNone, SkipBlanks:= _
******* False, Transpose:=False
*** Range("A11").Select
*** Application.CutCopyMode = False
End Sub

This system is used to track time elapsed. Example, the first event of the day begins, so I click the checkbox in A11 and the time appears in A11. When the event ends, I click the checkbox in O11 and the time appears in O11.

Now what I would like to modify is the following:

After clicking A11, if 30 minutes have elapsed and I still have not checked the end time in O11, I would like the whole row to highlight in red, a pop up message box should advise me that 30 minutes have elapsed. I could click OK and remove the message box. The whole row remains in red highlight until I finally check the checkbox in O11.

Obviously I'd copy the code for each row.

I assume the code goes with the checkbox's code for A11? Also, is it possible for a cell to flash? (highlighted white, then red, then white, red, etc...)

Tracking Elapsed Time With No Date

Mar 4, 2007

I have an assignment to audit the time it takes convert a printing press from one job to the next. I've been using a watch to take the readings in hours, minutes, and seconds.

I recorded them in my spreadsheet, as h:mm:ss, but it showed a date also. I think I finally got that resolved, but now, when I try to subtract one time from another time, I get an incorrect answer. I think I need to convert all of these times into decimals, as in 13.23.44, as oppossed to 13:23:44.

One post on page 1 of my search said to multiple A1*24, but I don't fully understand. I tried that, but 11:30 became 11.50?

I need to extract the set up time, or job to job changover time in a decimal format if possible. There are other tasks being done with those numbers later in the spreadsheet that are more conducive to decimals, than the time format.......

If Statement To Find The Elapsed Time

Apr 28, 2008

I'm trying to write an if statement to find the elapsed time. I want it to work so that if a time wasn't recorded, it looks to the previously recorded time to find the time in-between.

Here's what I have so far:

=IF($D18="",($F18-$N17)*1440,IF($N17="",($F18-$L17)*1440,IF($L17="",($F18-$J17)*1440,($F18-$D18)*1440)))

The problem I have when testing this formula is that D18 is not blank, so it should calculate (F18-D18)*1440. But it's not.. it's calculating (F18-N17)*1440. Here's a preview of my spreadsheet.

Get Excel To Calculate Elapsed Time Between Two Dates?

Apr 3, 2014

I have been trying to get excel to calculate elapsed time between two dates using mostly what I've read from other elapsed time posts. But I am clearly missing a step. I'm trying to streamline my process for taxes.

I want to take a time in the format of " yy/mm/dd hhmm " example: 1

3/04/24 2245 ( note its a 24hr clock) 13/04/24 2245 would represent 2013 April the 24th at 10:45PM.

------- A --------------- B -------------------- C
13/04/24 2245 ------13/05/24 0900 ---------[display hrs elapsed] <-- currently get #name?

I have custom formatted A and B to yy/mm/dd hhmm and formatted c to [h]:mm

When you enter b-a in column c you get #name?

If its easier to have the date and time into separate columns I can give that a shot, I was just trying to make it as streamlined as possible for copy past.

Date/calculate Elapsed Time Formula

Feb 16, 2010

I have been asked to make some ammendements to a workbook currently in use.

I have to calculate elapsed time, and my formula is giving me odd results. I have a start time (cell B5), and an end time (cell F5). The formula being used was =IF(F5>0,((F5-B5)*24)) which gave the correct result. The cell is formatted as general. It didn't alot for the situation where the end time has not happened yet.

I changed the formula to =IF(F5>0,((F5-B5)*24),(K5-B5)*24) where cell K5 is the current time. The results are coming out with 6 - 9 decimal places. It makes no sense as I've tried setting the times to be exactly 24 or 48 hours to the minute. I've also tried replacing K5 in the formula to now(),

Calculating Time Elapsed Between Days As Decimal

Aug 24, 2012

I'm building a schedule in excel and am having trouble with the calculation of total hours when lapsing a day, or more specific, adding it into my current equation. For example; Monday they clock in at 5pm and work till 1am. I have found a couple of ways to get the desired out come from this on it's own. I just add the value of a day if the out time is less than the in time, or if the out time minus the in time is less than 0.

However, I need to add this calculation into an equation that is already calculating time elapsed within a single day, turning that into a decimal number and then checking if the total time elapsed is less than 6 hours, if false it subtracts a thirty minute break. Here is the current equation I'm using, I'm sure that there is an if(or, or if(and I could use to make it work when the time lapses 12am while also performing the 6 hour check to subtract the break.

=IF(((F7-INT(D7))*24)-(D7-INT(F7))*24

Excel 2010 :: Calculating Average Elapsed Time

Apr 3, 2014

In our sql server table, we have a field of type DATETIME. This field is populated by a vendor product with the elapsed time of an event.

We created a SQL Server view of this column and other columns of info joined together from several tables.

Then we create in Excel 2010 a new spreadsheet with a data connection to the SQL Server, instance, and view that we created.

Excel 2010 displays each of the columns in our view.

The elapsed time column appears as "dd hh:mm:ss". However, when we click on a cell to look at its formatting, Excel lists it as general.

We want to calculate the average time in this column.

We go down below the data, click on a cell, and insert =Average(C2:C17215) and we get an error saying dividing by zero.

We have 17,000+ rows of data, so there is no divide by zero math going on here. Each row in this column has data, so there are no blank cells.

We have spent some time web searching. We then tried various methods of calculating this. Nothing has worked. In most cases, we get the divide by zero. We tried some solutions that mention using an array forumula, but that just changed the error to an invalid value error.

Calculating Elapsed Time,respecting Working Hours.

May 1, 2009

I am looking for a formula to calculate time from one date and time to another. The only catch is I only want it to use times during specific times.

Example

Start 5/1 8am and end 5/2 8am. The working hours are from 7am until 4pm and from 8pm till 5am. In this example the solution should be 17 hours.

How do I set up a formula to respect only working hours (also excluding weekends except for Saturday early am from midnight until 5am.

Sorry if this is confusing, I am trying to use IF statements but Im fighting a losing battle.

Time Calculation: Calculate How Many Hours Have Elapsed Between To Entries

Jun 22, 2009

I am trying to build a spreadsheet to calculate how many hours have elapsed between to entries; start time (H10) e.g. 9:15 AM and end time (I10) e.g. 12:15 PM. The formula that I am using in the calculation cell field (J10) is (I10-H10+(I10<H10))*24. This formula works great till I wish to include in an IF statement. What I would like is if the total hours calculated with the formula (I10-H10+(I10<H10))*24 is less than 4, return 4 (hours) otherwise the value. As well if there is no start time nor end time entered then return zero.
