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).
