Convert dates between ISO and Gregorian formats. new my $iso = Date::ISO->new( iso => $iso_date_string ); my $iso = Date::ISO->new( epoch = $epoch_time ); Set the time to 2:30:25 on the date specified in $iso_date_string my $iso = Date::ISO->new( iso...

This module is entirely identical to Date::Simple. It is included for completness and self documenting sake. IMO it is preferable to say my $obj=Date::Simple::ISO->new(...); As this makes the implicit formatting of the object clear....

The international standard ISO 8601 "Data elements and interchange formats - Information interchange - Representation of dates and times" defines three distinct calendars by which days can be labelled. It also defines textual formats for the represen...

Date::Tie is an attempt to simplify date operations syntax. It works with calendar dates (year-month-day), ordinal dates (year-day), week dates (year-week-day), times (hour:minute:second), decimal fractions (decimal hours, decimal minutes and decimal...

Simple methods for manipulating simple dates....

Date::WeekOfYear is small and efficient. The only purpose is to return the week of the year. This can be called in either a scalar or list context. In a scalar context, just the week number is returned (the year starts at week 1). In a list context, ...

For date and time calculations it is convenient to represent dates by a simple linear count of days, rather than in a particular calendar. This is such a good idea that it has been invented several times. If there were a single such linear count then...

Date::ICal talks the ICal date format, and is intended to be a base class for other date/calendar modules that know about ICal time format also....

Date::Tiny is a member of the DateTime::Tiny suite of time modules. It implements an extremely lightweight object that represents a date, without any time data. The Tiny Mandate Many CPAN modules which provide the best implementation of a concept can...

This module provides functions that deal the date formats used by the HTTP protocol (and then some more). Only the first two functions, time2str() and str2time(), are exported by default. time2str( [$time] ) The time2str() function converts a machine...

"Date::Parse" provides two routines for parsing date strings into time values. str2time(DATE [, ZONE]) "str2time" parses "DATE" and returns a unix time value, or undef upon failure. "ZONE", if given, specifies the timezone to assume when parsing if t...

The two functions provided by this module can be used to generate the week number in the year of a given date. For example: print "Today is in week ", iso_week_number(time()), "\n"; Which at the time I'm writing this will print: Today is in week 2014...

This module is intended to provide a general-purpose date and datetime type for perl. You have a Class::Date class for absolute date and datetime, and have a Class::Date::Rel class for relative dates. You can use "+", "-", "<" and ">" operators as wi...

This rule coerces date from a subset of ISO8601 string. Currently only the following formats are accepted: "YYYY-MM-DD" ; # date (local time), e.g.: 2016-05-13 "YYYY-MM-DDThh:mm:ss" ; # date+time (local time), e.g.: 2016-05-13T22:42:00 "YYYY-MM-DDThh...

Dates are complex enough without times and timezones. This module may be used to create simple date objects. It handles: Validation. Reject 1999-02-29 but accept 2000-02-29. Interval arithmetic. How many days were between two given dates? What date c...

This module implements a small and simple object for representing a date. Its scope is intentionally limited to the kind of applications that require very basic date functionality with minimal overhead. For any non-trivial date manipulation you shoul...

Date::Holidays is an adapters exposing a uniform API to a set of dsitributions in the Date::Holidays::* namespace. All of these modules deliver methods and information on national calendars, but no standardized API exist. The distributions more or le...
