SYMPTOMSWhen you enter a formula that uses the DATE function, the date returned by the function may not be what you would expect. For example, if you enter this formula
the formula returns 1/2/3799 and the expected result is 1/2/1899.
CAUSEThe versions of Microsoft Excel listed at the beginning of this article recognize a larger range of date values than do earlier versions of Excel. Excel treats year parameters that are less than 1900 as offsets of 1900. The difference with Excel 97 and later is that with a year value that is greater than 178 and less than 1900, it results in a year that is greater than the supported range in Excel 95 and earlier, but within the supported date range of Excel 97 and later. These differences are listed in the following table.
Note that if a workbook is using the 1904 date system and if the DATE
function returns a date from 1900 through 1903, the function returns a
#NUM! error value. For more information, please see the following article
in the Microsoft Knowledge Base:
Q175753 XL: DATE Function May Return #NUM! Error When Year Is 0-3 MORE INFORMATION
Earlier versions of Microsoft Excel can handle only dates from 1/1/1900
through 12/31/2078; the versions of Microsoft Excel that are listed at the
beginning of this article can handle dates from 1/1/1900 through
12/31/9999.
Because the year argument (98) is less than 1900, Microsoft Excel adds
1900 to the argument (1900 + 98 = 1998) and returns the following date:
7/5/1998Because earlier versions of Microsoft Excel cannot handle dates greater than 12/31/2078, if the value of the year argument becomes larger than 2078, the DATE function returns a #NUM! error value. This is normal behavior for earlier versions of Microsoft Excel. However, because Microsoft Excel 97 can handle dates through the year 9999, you do not receive a #NUM! error value unless the value of the year argument is greater than 9999.
