Answer 1

Use the MySQL built-in function week to find the week number for the year, then subtract the week number for the first day of the month.

SELECT WEEK('2012-02-20') - WEEK('2012-02-01')

there are plenty of options in the documentation to customize the call to fit exactly what you are looking for, but I hope my example gives you an idea of what is available to you.
