Iterate every month with date objects

Question

So I have two ruby Date objects, and I want to iterate them every month. For example if I have Date.new(2008, 12) and Date.new(2009, 3), it would yield me 2008-12, 2009-1, 2009-

Answer 1

Here is something very Ruby:

first day of each month

(Date.new(2008, 12)..Date.new(2011, 12)).select {|d| d.day == 1}

It will give you an array of the first day for each month within the range.

last day of each month

(Date.new(2008, 12)..Date.new(2012, 01)).select {|d| d.day == 1}.map {|d| d - 1}.drop(1)

Just note that the end date needs to be the month after your end range.
