Hi All,

I have a time series data with two continuous variables (say Var1 and Var2)
for 4 years (***not continuous, do have some breaks because of missing
data***). Something like this:

Date Var1 Var2
12/01/2004 7 0
12/01/2004 0 0
12/01/2004 0 7
12/01/2004 7 0
12/01/2004 0 7
12/01/2004 0 7
12/02/2004 0 0
...

I need to find out weekly average of var1 and var2, so that I end up with
data like:

 Week Year Var1 Var2
week1 2004 2 3
week2 2004 4 2
...
week52 2004 4 4
week1 2005 2 3
...

Can anyone help please, any help would be greatly appreciated. Thanks!
