Class Method Details

.parse(date) ⇒ Object

Parse dates into yyyy-mm-dd format, preferring European over US convention. Returns nil on error.

Date.parse('1955-11-09')       # => '1955-11-09'
Date.parse('02/03/2009')       # => '2009-03-02'
Date.parse('02/23/2009')       # => '2009-02-23'
Date.parse('16th June 1986')   # => '1986-06-16'

Note that the parse method of the Date class behaves differently in Ruby 1.8 and 1.9. In 1.8 it assumes American dates and will raise ArgumentError on “30/03/2003”. In 1.9 it assumes European dates and will raise ArgumentError on “03/30/2003”.
