Answer 1

This works form me

Just make sure both dates in the below query are the same...

SELECT ('2017-10-07' - INTERVAL WEEKDAY('2017-10-07') Day) As `mondaythisweek`

This query returns: 2017-10-02 which is a monday,

But if your first day is sunday, then just subtract a day from the result of this and wallah!
