Calendars define some notation to identify days in history. The Gregorian calendar, now in wide use, was established by Pope Gregory XIII in AD 1582 as an improvement over the less accurate Julian calendar that had been in use before. Both of these c...

*Date::Gregorian::Exact* was a subclass extending Date::Gregorian towards higher precision (sufficient to deal with timestamps). Due to the simplicity of its data model, however, it never came close to satisfyingly handle real-life timestamps. Theref...

Represents the Gregorian date....

*Date::Gregorian::Business* is an extension of Date::Gregorian supporting date calculations involving business days. Objects of this class have a notion of whether or not a day is a business day and provide methods to count business days between two ...

Fucntion can be split into several categories: * Universal functions available for all subclasses (ie. all formats). The fundamental conversion routines fit this category. * Functions that are useful but don't necessarily make sense for all subclasse...

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 simple module converts gregorian dates to islamic (hijri) and vice versa. The dates must be given as an array containing the day, month and year, and return the corresponding date as a list with the same elements....

Date::Japanese::Era handles conversion between Japanese Era and Gregorian calendar....

See the README as for now. By the way, I want to be neutral to the calender system - that's why the SYNOPSIS above looks like it does. Personally I think Gregorian dates sucks a lot - but I'm living in a Gregorian world and I'm myself mostly thinking...

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....

Common date functions as Moo Role. It is being used by the following distributions: * Date::Bahai::Simple * Date::Gregorian::Simple * Date::Hebrew::Simple * Date::Hijri::Simple * Date::Julian::Simple * Date::Persian::Simple * Date::Saka::Simple...

This module defines a class for handling Roman dates as defined by Julius Caesar in 45 BC....

Calculates Easter for a given year. easter() is, for the moment, an alias to gregorian_easter(), since that's what most people use now. The thought was to somehow know which of the other methods to call, that that proved to be rather sticky....

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 is not a calander generator. It helps to wirte one by providing essential and auxillary services. Services offered by this module are: 1. Sun rise/set. 2. Moon rise/set. 3. Tithi at a given time. 4. Moon's constallatation at a given time....

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...
