DateIterator

---

Iterate by day, week, or month - inclusive

• Tested on CRuby: 2.1, 2.2 (but should work at least from 1.8.7)
• adds 3 instance methods to Date:
  • each_day_until
  • each_week_until
  • each_month_until
  • If no block is given, returns an enumerator.

Usage

>> Date.parse("2010-01-01").each_day_until("2010-01-05") { |d| puts d }
