if you give it the first date of the year you want the week to start on then you can use <br>Dateadd("ww",[weeknumber]-1,weekstart)then do <br>Dateadd("ww",[weeknumber]-1,weekstart)+6 to get week end date<br>example this year the first week started 1/2/2000 so week 2 would start 1/9/2000<br>good luck
