The serial number of an Apple product has (almost always) the manufacture date encoded. For a CPU, first two characters of the serial number is the factory code, next three are the year (one digit only), and week. So, for my MacBook Pro, the serial number 'WQ929xxxxxx' indicates the twenty-ninth week of 2009 as the date of manufacture. The format could change, of course, but this has been the pattern for years. Under the Apple menu, 'About This Mac' can be selected, to show the serial number, or you can hunt the case of an iPad or iMac for a label.

In case of a repair and motherboard replacement, the software might no longer know that serial number.

Excel stores dates in sequential serial numbers beginning with January 1st, 1900 as 1. January 1st, 2006 is 38718 because it's 38,718 days after January 1st, 1900.

Excel on MAC works the same, except the dates start on January 1st, 1904. Don't ask me why.

Note: Some of these formulas and functions use a named range called 'Holidays'.

To create it, make a list of dates in a column. To the cells. Tip: Volatile formulas are formulas that recalculate every time the workbook calculates. The =NOW formula (among others) is a Volatile formula. If you open a workbook that contains a volatile formula, you make no changes, and close it, don't be surprised if you're asked to save the workbook. That's because the value that the recalculation created did, in fact, change in your workbook. OfficeArticles.com debuted on May 26, 2005.
