SUMMARY
Microsoft Excel limits the maximum time value that you can enter into a cell or return by using a formula. This article describes the limits in different versions of Microsoft Excel.



MORE INFORMATION
In the versions of Microsoft Excel listed at the beginning of this article, you can enter times that exceed 24 hours by using a number format that includes "[h]" (without the quotation marks). The square brackets around the "h" instruct Microsoft Excel to calculate times beyond 24-hour intervals, which permitss you to enter times that exceed 24 hours. If you enter a time that exceeds 24 hours, Microsoft Excel automatically applies a number format that includes the "[h]" code.

There are limits that apply to times that use this format. If you type a time into a cell or use a formula to return a time that exceeds the limits, you may notice either of the following problems:

 If you enter a time that exceeds the limits, the time may appear as a text string.

For example, if you enter the following time in Microsoft Excel 98 Macintosh Edition

20000:00:00

the time appears in the cell as a text string that is left-aligned.  If you use a formula to return a time that exceeds the limits, the formula returns a series of number signs (####).

For example, if you use the following values and formulas in a worksheet in Microsoft Excel 5.0      A1: 12/31/2078 23:00:00 A2: 1:00:00 A3: =A1+A2 the formula returns a series of pound signs because the time returned by the formula exceeds the maximum time for Microsoft Excel 5.0. 

Microsoft Excel for the Macintosh, versions 5.0, 5.0a
The maximum time that you can enter into a cell is 1569143:59:59. This time is equivalent to 12/31/2078 23:59:59, which is the maximum time you can use in these versions of Microsoft Excel.

The maximum time that you can calculate using a formula is also 1569143:59:59.

Microsoft Excel 98 Macintosh Edition and Later
The maximum time that you can enter into a cell is 9999:59:59. If you enter a time that is greater than or equal to 10,000 hours (10000:00:00), the time appears as a text string.

The maximum time that you can calculate using a formula is 71003183:59:59. This time is equivalent to 12/31/9999 23:59:59, which is the maximum time you can use in Microsoft Excel 98 Macintosh Edition and later.
