parse(str='-4712-01-01', comp=false, sg=ITALY)
public
Create a new Date object by parsing from a String, without specifying the format.
str is a String holding a date representation. comp specifies whether to interpret 2-digit years as 19XX (>= 69) or 20XX (< 69); the default is not to. The method will attempt to parse a date from the String using various heuristics; see #_parse in date/format.rb for more details. If parsing fails, an ArgumentError will be raised.
The default str is ’-4712-01-01’; this is Julian Day Number day 0.
sg specifies the Day of Calendar Reform.
