In Microsoft Excel, there are limits to the maximum time values that you can enter into a cell or return by using a formula. This article explains those limits.
In Microsoft Excel 5.0 and in later versions of Excel, you can enter times that exceed 24 hours by using a number format that includes [h]. The square brackets around the "h" instruct Excel to calculate times beyond 24-hour intervals, which allows you to enter times that exceed 24 hours. If you enter times that exceed 24 hours, 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 value into a cell or use a formula to return a time that exceeds the limits, you may notice either of the following behaviors:
The maximum time value that you can calculate using a formula is 71003183:59:59. This value equates to 12/31/9999 23:59:59, which is the maximum time that you can use in Excel 2000.
