Combine current year and last year sales by date

Hi,

We want to show sales as follows

Date    current year sales   last year sales

We have special calendar , where last year date will not be same as -365 days .Hence relative date doesn't work out.

Ex,

I created 2 tables ,

Current year table from query 1

Last year table from query2

Expected output

I tried to merge year date from query1 to relative date fromquery2, but merge is greyed out.

Any input would be appreciated

Thanks

Ben
