Hi,

I need to get the corresponding day 52 weeks ago, so if I have a Tuesday I need to get the corresponding Tuesday 52 weeks ago ...

Since there is no method addweeks(DATE, -52), how is the best way to solve this issue?

Best regards
& thanks in advance

Hi Stefan,

Try this :

Date(YourDate - (52*7)) as SameDayLastYear

Obviously there is no need for AddWeek function because a week is always exactly 7 days...

you can also add Day# in Year to your master calendar, obviously this will vary on leap years but works great.  I also add Business Day# in Year and you can even exclude business holidays
