You can try this way

require 'active_support/core_ext/date/calculations'

monday = (Date.today.beginning_of_week.last_week)

sunday = (Date.today.beginning_of_week.last_week + 6)

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)>

Use Date#wday that tells with day of the week is for a given Date and then subtract accordinglly:

require 'date'

date = Date.parse("15-02-04")
monday = date - (date.wday + 6) # 2015-01-26
sunday = date - date.wday # 2015-02-01

date = Date.parse("15-02-27")
monday = date - (date.wday + 6) # 2015-02-16
sunday = date - date.wday # 2015-02-22
