In Ruby step method iterates evaluation of the given block, which takes a date object. The limit should be a date object. For example,
1 2 3 4 5 6 7 | # import date library require 'date' # on 2012,1,1 the day was Sunday x = Date.new(2012).step(Date.new(2012,1,1)).select{|d| d.monday?}.size # on 2012,1,2 first monday of that year x = Date.new(2012).step(Date.new(2012,1,2)).select{|d| d.monday?}.size puts x |
Output:
01NOTE: From the above example, it is easy to understand that .step method iterates until it find the required day which is also indicated in the code. This code tells that, this is the first monday of that particular year.

8Use of Step Method in Ruby with Example
1 2 3 4 5 6 | # import date library require 'date' # you can get desired year x = Date.new(2012).step(Date.new(2012,3,12)).select{|d| d.monday?}.size x = Date.new(2012).step(Date.new(2012,4,16)).select{|d| d.monday?}.size puts x |
