DateOffset ( startdate ; monthoffset ; dayoffset ; yearoffset)

Erik Wegweiser, Intelligent Database
http://intelligentdb.com

Returns a start date, plus or minus a specified number of months, days or years.

Sample Input:
DateOffset ( tuday ; -18 ; 7 ; 0)
Sample Output:
3/29/2006 [ if tuday is 9/22/2007]


 Then copy & paste into FileMaker Advanced's Edit Custom Function window.

if you have myFMbutler's Clip Manager installed

Description:

Returns a start date, plus or minus a specified number of months, days or years. For example, avoids the need for substituting the less accurate "365 * 1.5" (or 547 or 547.5? or 548) for an 18-month offset in date calculations. Also makes it easier to read and remember that the date is adjusted by 18 months (rather than remember what 547 days represents).

Note: these functions are not guaranteed or supported by BrianDunning.com. Please contact the individual developer with any questions or problems.
