I know there's a better algorithm to do this, but this might work... function olddate(thedate, offset) * parameters: thedate: date to start from * offset: number of years offset, positive or negative * returns: nearest date to the offset that falls on the same day of the week local thedow, thenewdow, thediff, theoffset thedow = dow(thedate) thenewdow = dow(gomonth(thedate, offset*12)) thediff = thedow - thenewdow theoffset = iff(thediff>3, 7-thediff, thediff) return gomonth(thedate, offset*12) + thediff _______________________________________________ Post Messages to: [email protected] Subscription Maintenance: http://mail.leafe.com/mailman/listinfo/profox OT-free version of this list: http://mail.leafe.com/mailman/listinfo/profoxtech Searchable Archive: http://leafe.com/archives/search/profox This message: http://leafe.com/archives/byMID/profox/CACW6n4u4nczhZe8=v3n2zcnattpn2tjdvmdigxbxorpe8xi...@mail.gmail.com ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
