Expanding on iggy's answer, here is the query to get the days of the week. Adjust the query to set the first day of the week as necessary.

SELECT current_date AS `Date`,
       CASE date_format(current_date,'u')
           WHEN 1 THEN 'Mon'
           WHEN 2 THEN 'Tues'
           WHEN 3 THEN 'Wed'
           WHEN 4 THEN 'Thu'
           WHEN 5 THEN 'Fri'
           WHEN 6 THEN 'Sat'
           WHEN 7 THEN 'Sun'
END AS day_of_week
