Overview

Attempts in part to make the Date class do everything (or at least some of the things) that the Time class can do (ActiveSupport::CoreExtensions::Time::Calculations). Maybe that would be better accomplished with a method_missing() that calls to_time.send(:the_same_method) if Time.respond_to?(:that_method).

#date_for_report ⇒ Object

These should be moved elsewhere because they are subjective and depend on the context where they’re used.

#month_step(max, step, &block) ⇒ Object

This is based on the implementation of Time.step. The main difference is that it uses >>= (increment by 1 month) instead of += (increment by 1 day).

  time = self

  while time.__send__(op, max)
    block.call time
    time >>= step

end

#months_upto(max, &block) ⇒ Object

Step forward one month at a time until we reach max (inclusive), yielding each date as we go
