** Please Note:** This article is written for users of the following Microsoft Excel versions: 97, 2000, 2002, and 2003. If you are using a later version (Excel 2007 or later),

If you format a cell for elapsed time (using a custom display format of [h]:mm:ss), then Excel allows you to enter hours, minutes and seconds into that cell. For instance, you could simply enter 129:14:30 to signify 129 hours, 14 minutes, and 30 seconds. You run into a problem, however, if you try to enter very large time values into the cell. When you try to enter time values in excess of 10,000 hours, as in 12721:52:45, then Excel won't parse the entry as a time, but treats it as text.

The interesting thing is that when a cell is formatted for elapsed time using [h]:mm:ss, the cell can easily display elapsed times that have more than 10,000 hours. Thus, you can sum a range of cells to result in a value more than 10,000 hours, but you cannot enter a larger value.

Unfortunately, there seems to be no way around this in Excel. The best solution, however, might be to rethink how the data is entered. After all, 10,000 hours is equal to 416 days and 16 hours—well over a year. You could easily create a column for entering days and use another for partial days. A third column could then use a formula to return the elapsed hours based on the other two columns.

Another solution is to simply not rely on Excel to do the parsing of your input. If you have a huge number of hours to enter (such as 32,315), then you could enter the following in the cell:

=32315/24

Excel maintains what you enter as a formula, but displays the proper number of hours, minutes, and seconds. If you want to get more precise, you can enter a fractional amount that represents the portion of an hour represented by your time. For instance, 37 minutes and 15 seconds is 0.620833 of an hour. Thus, you could enter the hours as follows:

=32315.620833/24

Of course, entering times in this manner can get tedious, particularly when you have calculate the fractional portion of an hour represented by minutes and seconds. To overcome this, you could create a custom function that allows you to enter hours, minutes, and seconds, and returns a value that is easily formatted using the elapsed time format. The following function will do the trick:

Public Function RealBigTime(hr As Double, _ min As Double, sec As Double) As Double Dim hr1 As Double Dim min1 As Double Dim sec1 As Double Application.Volatile hr1 = hr / 24 min1 = min / 24 / 60 sec1 = sec / 24 / 60 / 60 RealBigTime = hr1 + min1 + sec1 End Function

After creating the function, enter something like =RealBigTime(32341,30,45) in a cell. The result is a value that can be formatted with the elapsed time format to 32341:30:45.

Thanks for your post as it helped me find a solution to the same problem. By the way this is how I fixed my problem:

Say I had this 100709:10:20 and wanted to put it in a cell formated as [h]:mm:ss

1. I converted the time above to seconds on a temporary empty like this =(60*60*100709)+(60*10)+20 which gave me 362553020 seconds.

2. I then simply went to the cell I wanted to fill and converted the seconds back to normal time with this formula = 362553020/86400 and the problem was solved just like that.

Thanks again

I just use a simple formula for hours minutes and seconds and then apply the [h]:mm:ss format.

For 32341:30:45 enter:

=32341/24 + 30/60/24 + 45/60/60/24

Then the apply the proper time format.

For 32341:30:45 enter:

=32341/24 + 30/60/24 + 45/60/60/24

Then the apply the proper time format.

I found a work around, but it's a little bit of a pain. For my situation I had to find a way. So if you enter 24:00 into the cell it is equal to 1/1/1900 12:00:00 AM in the upper box where you would enter formulas. So if you need the cell to be 10000:00, you have to manualy change the date up top.So 10000 hours = 1 year,51 days, and 16 hours ruffly. So add that to 1/1/1900 12:00:00 AM should be changed to 2/19/1901 4:00:00 PM to equal 10000: hours
