Use methods beginning_of_month

andend_of_month 



irb(main):004:0> n = DateTime.now
=> Wed, 10 May 2017 14:48:01 +0300
irb(main):005:0> n.to_date.beginning_of_month
=> Mon, 01 May 2017
irb(main):006:0> n.to_date.end_of_month
=> Wed, 31 May 2017

Given the year and month:

year = 2017
month = 5


You can pass them in Date.new

along with the daily value 1

and -1

to get the first and last day respectively:

require 'date'
Date.new(year, month, 1)  #=> #<Date: 2017-05-01 ...>
Date.new(year, month, -1) #=> #<Date: 2017-05-31 ...>
