Product Details

Summary:

The way that Microsoft Works 4.0 for the Macintosh interprets dates that are entered with a 2-digit year value is dependent on the current date setting for the operating system and is summarized in the table below. This product was designed to store dates as serialized numbers, regardless of the visual cell format chosen by the user. Users do not have to go back into files/records and change dates to 4-year format.

How the product handles dates:

Storage:

Microsoft Works 4.0 for the Macintosh stores dates internally as serial numbers from 0 to 49710, where 0 is the serial number for January 1, 1904 and 49710 is the serial number for February 6, 2040. For example, if the date 1/1/1905 is entered, Microsoft Works stores it internally with a value of 366 since this is the number of days since (and including) the serial starting point of January 1, 1904. If the date 6/1/1998 is entered, Microsoft Works stores it internally with a value of 34485 and so on, since this is the number of days since the starting point of 1/1/1904. In addition, Microsoft Works stores 4-digit years in files even when entry uses only 2 digits.

Two-Digit Shortcut Handling:

If a date is entered with a 2-digit year (i.e. 6/1/98), Microsoft Works 4.0 for the Macintosh has four distinct behaviors, depending on four distinct system date ranges. The table below describes how Microsoft Works 4.0 for the Macintosh interprets a 2-digit year value depending on the current system date (which is set in the operating system):

Sorting:

Microsoft Works 4.0 sorts on full years (4-digit dates) even if only 2 digits are displayed. Also, Microsoft Works 4.0 sorts dates when some are prior to 2000 and some are after 2000.

Leap Years:

Microsoft Works 4.0 executes leap years and displays 2/29 in appropriate years, including the year 2000 and after.

Display:

Users can select several different visual formats for dates, without changing the underlying value of the actual date itself. The formula bar in the Spreadsheet will display a 4-digit year (YYYY) regardless of the cell format (YY or YYYY). The formula bar in the Database will display the year as 2 or 4 digits, mirroring the default system date format.

Additional Information:

The DATE() function (which can be used to build formulas in the spreadsheet and database) is not designed to take 2-digit year shortcuts, since it receives numeric parameters. For the Year argument of the DATE() function, numbers less than 1900 are calculated as an offset from 1900. Year arguments with a value of 1900 or greater are interpreted as the 4-digit year value they represent. So, if you were to enter a formula such as =DATE(15,1,1), the resulting date would be January 1, 1915, not 2015. If you were to enter a formula such as =DATE(115,1,1), the resulting date would be January 1, 2015. Similarly, if you were to enter a formula such as =DATE(2015, 1, 1) the resulting date would be January 1, 2015.
