Answer 1

You can try this way:

require 'date'
=> true

date = Date.today
=> #<Date: 2015-02-04 ((2457058j,0s,0n),+0s,2299161j)>

# date.wday return week day
end_date = date-date.wday
=> #<Date: 2015-02-01 ((2457055j,0s,0n),+0s,2299161j)>

start_date = date-date.wday-6
=> #<Date: 2015-01-26 ((2457049j,0s,0n),+0s,2299161j)>
