Changing Excel's Starting Date

Written by Allen Wyatt (last updated April 19, 2025)
This tip applies to Excel 97, 2000, 2002, and 2003

Excel allows you to choose which arbitrary date you use as the beginning point for serial numbers. In the PC world, this date is January 1, 1900. If you are working with Excel workbooks imported from the Macintosh environment, however, you will want to set the starting date to January 2, 1904—the date used on the Mac.

To set which of these two dates is used, follow these steps:

  1. Choose Options from the Tools menu. Excel displays the Options dialog box.
  2. Make sure the Calculation tab is selected. (See Figure 1.)

    3. Figure 1. The Calculation tab of the Options dialog box.

  3. The 1904 Date System check box controls which dating system is used. If the check box is not selected, then the January 1, 1900 starting date is used; if it is selected, then January 2, 1904 is used.
