How to find start date of particular yearweek in mysql?

Question

I have yearweek of buch of records. I need to find star date and end date of that particular yearweek in mysql. Note here any date is not dependent upon curdate(). Any possible?

Answer 1

I would try something like
STR_TO_DATE(yearweek_data, '%X%V')

But this may not be enough as the docs says also the name of the day may be required to uniquely identify the date. Check details here
