How to make the 'week' starts with a specific day not Monday?

In an application am building, i'm trying to make the week starts with Saturday. In ruby on rails, by default, the week begins on Monday.

So If you have any trick or a patch to make it work for me!

Thanks in advance!

I've managed to make a pull request into rails and now you can pass symbol argument to beginning_of_week method. For example beginning_of_week(:sunday) will give you a Sunday assuming that week starts on Sunday. The same for end_of_week method. But you have to wait until rails 3.2 release in case you are not on the bleeding edge.

See this for more info: https://github.com/rails/rails/pull/3547

UPDATE: Now I'm waiting for the new PR to be accepted, it makes possible to set default week start in your rails app config. See this for more info https://github.com/rails/rails/pull/5339

UPDATE:

Merged!

You could throw this into an initializer to make beginning_of_week return Sunday:

module ActiveSupport #:nodoc:
  module CoreExtensions #:nodoc:
    module Time #:nodoc:
      module Calculations
        def beginning_of_week
          (self - self.wday.days).midnight
        end
      end
    end
  end
end

It may be safer however for you to define your own method and leave the stock one intact:

module ActiveSupport #:nodoc:
  module CoreExtensions #:nodoc:
    module Time #:nodoc:
      module Calculations
        def traditional_beginning_of_week
          (self - self.wday.days).midnight
        end
      end
    end
  end
end

You can try replacing Date#wday and Time#wday methods with your own. I think Rails' support methods like beginning_of_week etc. rely on wday and will work out of the box.

Here's some code, but it's definitely just an idea, neither tested nor recommended thing to do:

require 'activesupport'
#=> true
Time.now.wday
#=> 4
Time.now.beginning_of_week
#=> 2010-04-19 00:00:00 0200

class Time
  alias_method :orig_wday, :wday
  def wday 
    (self.orig_wday + 2) % 7
  end
end

Time.now.wday
#=> 6
Time.now.beginning_of_week
#=> 2010-04-17 00:00:00 0200
