I've seen an alternate version where +0 is used after the year/month/day functions.
What's the reason for the -0 or +0 in this formula ?

your sample above for plus or minus two weeks doesn't work in a leap year, so it's not a very good sample because it is relying on numbers (like 7) instead of thinking like a calendar.
