Answer 1

I am not sure how to get the output you are looking for -- I'm simply not sure what it means. However, you can set the first day of the week using DATEFIRST . This applies to most of the functions, such as DATEPART .

The documentation is here .

Answer 2

for MySQL

select (dayofmonth(current_date)-weekday(current_date))/7+1

PostgreSQL

select (extract(day from current_date)-extract(dow from current_date))/7 +1;

just put your date in the current_date
