CHANGES 1.03: Fixed bug where 'prev' did the same as 'next': D'Oh! NAME Date::Simple - a simple date object SYNOPSIS my $date = Date::Simple->new('1972-01-17'); my $year = $date->year; my $month = $date->month; my $day = $date->day; my $date2 = Date::Simple->new($year, $month, $day); my $today = Date::Simple->new; my $tomorrow = $today + 1; print "Tomorrow's date (in ISO 8601 format) is $tomorrow.\n"; if ($tomorrow->year != $today->year) { print "Today is New Year's Eve!\n"; } if ($today > $tomorrow) { die "warp in space-time continuum"; } DESCRIPTION This module may be used to create ISO 8601 simple date objects. It only handles dates within the range of Unix time. It will only allow the creation of objects for valid dates. Attempting to create an invalid date will return undef. CONSTRUCTOR new my $date = Date::Simple->new('1972-01-17'); my $otherdate = Date::Simple->new(2000, 12, 25); The new method will return a date object if the values passed in specify a valid date. If an invalid date is passed, the method returns undef. INSTANCE METHODS next my $tomorrow = $today->next; Returns an object representing tomorrow. prev my $yesterday = $today->prev; Returns an object representing yesterday. year my $year = $date->year; Return the year of the date held in this date object month my $month = $date->month; Return the month of the date held in this date object day my $day = $date->day; Return the day of the date held in this date object format Returns a string representing the date, in the format specified. If you don't pass a parameter, an Simple 8601 formatted date is returned. my $change_date = $date->format("%d %b %y"); my $iso_date1 = $date->format("%Y-%m-%d"); my $iso_date2 = $date->format; The formatting parameter is uncannily similar to one you would pass to strftime(3). This is probably because we actually do pass it to strftime to format the date. OPERATORS Some operators can be used with Date::Simple instances: * You can increment or decrement a date by a number of days using the += and -= operators * You can construct new dates offset by a number of days using the + and - operators. * You can subtract two dates ($d1 - $d2) to find the number of days between them. * You can compare two dates using the arithmetic comparison operators. * You can interpolate a date instance directly into a string, in the format specified by ISO 8601 (eg: 2000-01-17).
