Hello everyone!

I hope you can help me. Here is my problem:

I have a machine that keeps track of its operating hours. Hours: Adding minutes is not the problem, but the machine already has over 15000: 00 operating hours on the clock and if I then want to add 1:23 hours, for example, the #Value! Error occurs.
If I start with 9999: 59 hours there is no problem.

Can someone help me?

Greetings Roman

Hello Roman,

which cell formats do you use?

[hh]: mm

would be correct.

Or could it be that the cell containing the time to be added is formatted as text?
The error does not occur for me.

Yes, I use the format [hh]: mm

and as soon as I start with 9999: 59 I have no problem.

But I have to (want to) start with 19227: 34 and then it doesn't work anymore. Greetings Roman

Hello Roman,

The following is written in the Excel Limitations.
 Code: Excel 97: 9999: 59: 59 Excel 2000: 9999: 59: 59 Excel 2002: 9999: 99: 99 => 9999: 59: 59 Excel 2003: 9999: 59: 59 The time 9999: 59: 59 corresponds to 02/19/1901 3:59:59 or 02/20/1905 3:59:59 if the 1904 date system is used. To calculate with consecutive hours, the number format "[h]: mm" (or "[h]: mm: ss") is used. This means that hours greater than 23 are not converted into days. Since this number format represents a time, it is subject to the limitation described here. The largest number of hours that can be entered in a cell is 9999. Excel does not recognize the number 10000 and greater as the time and consequently it is displayed as text and treated as such (i.e. you cannot calculate with the "number"). However, times greater than 9999 can be calculated and displayed correctly. For example, the time is 9999: 00 * 2 = 19998: 00. Please note, however, that you cannot simply enter '= 9999: 00 * 2' in a cell (despite the correct time format), as this formula is invalid due to the colon character. If you enter '= 9999 * 2' instead, the result is 479952: 00, which is incorrect because Excel in this case regards the number 9999 as the number of days. In order for Excel to calculate correctly, the time must be written in inverted commas. The correct formula is therefore '= "9999: 00" * 2'. As an alternative, you could also write '= VALUE ("9999: 00") * 2'. Note that the formula '= VALUE ("10000: 00") * 2' returns the error value "#VALUE!" supplies. The greatest existing time with consecutive hours is 71003183: 59: 59. It corresponds to the time 12/31/9999 23:59:59. As mentioned above, this number of hours cannot be entered directly in a cell, as the maximum permitted time is 9999:59:59. If the result of a formula is greater than 71003183: 59: 59, the familiar garden fence appears in the formula cell (255 times the # sign). (Many thanks to Dr. Max Becke for his advice on this topic) Danger: The Microsoft Excel 2002 / XP reference states that the maximum permitted time is "9999: 99: 99". This information is clearly wrong. The specification should correctly read "9999: 59: 59".

Thank you Rainer for your help.

Unfortunately, I can't figure it out very well, but it doesn't matter. I'll find a solution somehow (sooner or later) Greetings Roman

 Hello fuexchen, try Rainer's hint as follows: A. B. C. 1 19227:34 01:23 19228:57 2 19228:57 01:35 19230:32
Formulas of the table
A1: = "9227: 34" + "9000: 00" + "1000: 00"
C1: = A1 + B1
A2: = C1
C2: = A2 + B2
