Getting dates from weeknumber

Rails
1

If I have a weeknumber and a year, is there an easy way to get the
dates that fall in this weeknumber or the first day of that week (the
other I can calculate).

Found it myself :slight_smile:

Date.neww(2007,5,6)

Input year, week and daynumber all in the commercial calendar and you
get a date back.

require ‘date’

def sunday_before( d )
d - d.wday
end

def start_of_week( week_number, year )
sunday_before( Date.new( year, 1, 1 ) ) + (week_number * 7)
end

puts start_of_week( 0, 2007 )
puts start_of_week( 1, 2007 )
puts start_of_week( 51, 2007 )
puts start_of_week( 52, 2007 )
puts start_of_week( 53, 2007 )
