Method: Date.strptime

Defined in:

date_core.c

.strptime([string = '-4712-01-01'[, format='%F'[, start=Date::ITALY]]]) ⇒ Object

Parses the given representation of date and time with the given template, and creates a date object. strptime does not support specification of flags and width unlike strftime.

Date.strptime('2001-02-03', '%Y-%m-%d')	#=> #<Date: 2001-02-03 ...>
Date.strptime('03-02-2001', '%d-%m-%Y')	#=> #<Date: 2001-02-03 ...>
Date.strptime('2001-034', '%Y-%j')	#=> #<Date: 2001-02-03 ...>
Date.strptime('2001-W05-6', '%G-W%V-%u')	#=> #<Date: 2001-02-03 ...>
Date.strptime('2001 04 6', '%Y %U %w')	#=> #<Date: 2001-02-03 ...>
Date.strptime('2001 05 6', '%Y %W %u')	#=> #<Date: 2001-02-03 ...>
Date.strptime('sat3feb01', '%a%d%b%y')	#=> #<Date: 2001-02-03 ...>
