NAME

Gedcom::Date - Perl class for interpreting dates in Gedcom files

SYNOPSIS

use Gedcom::Date;

my $date = Gedcom::Date->parse( 'ABT 10 JUL 2003' );

my $dt = DateTime->now;
my $date2 = Gedcom::Date->from_datetime( $dt );

$date->gedcom;        # 'ABT 10 JUL 2003'
$date->as_text;       # 'about 10 July 2003'
$date->as_text('nl'); # 'rond 10 juli 2003'   (nl = Dutch language)

DESCRIPTION

The Gedcom standard for genealogical data files defines a number of date formats. This module can parse most of these formats.

This package contains a number of modules, each implementing a Gedcom date format. They are:

Gedcom::Date::Simple
  e.g. "4 JUN 1729", "JUL 2003", "1974"

Gedcom::Date::Approximated
  e.g. "ABT 15 JUN 1672", "CAL 1922", "EST 1700"

Gedcom::Date::Interpreted
  e.g. "INT 12 APR 1657 (Easter Monday)"

Gedcom::Date::Period
  e.g. "FROM 1522 TO 1534", "FROM 30 APR 1980", "TO 1910"

Gedcom::Date::Range
  e.g. "BET 1600 AND 1620", "AFTER 1948", "BEF 2 AUG 2003"

Gedcom::Date::Phrase
  e.g. "(Once upon a time)"

METHODS

Class methods

  • parse( $date )

    Creates a Gedcom::Date object from a string. The string should be a valid date value according to the Gedcom standard v5.5.

  • from_datetime( $datetime_object )

    Creates a Gedcom::Date object from a DateTime object. The return value is a Gedcom::Date::Simple object.

  • DefaultLocale( $locale )

    If called with one argument, sets the default locale used in output routines. If called without arguments, returns the current default locale.

Instance methods

  • earliest

    Returns the earliest possible date; e.g. for the date "BET 10 JUL 2003 AND 20 JUL 2003" it returns July 10, 2003. The value returned is a DateTime object.

  • latest

    Returns the latest possible date; e.g. for the date "BET 10 JUL 2003 AND 20 JUL 2003" it returns July 20, 2003. The value returned is a DateTime object.

  • gedcom

    Returns the date in Gedcom format.

  • as_text( $locale )

    Returns the date in a format that can be included in a narrative text. You can set the language of the text by passing an optional locale argument. This should be a DateTime::Locale object, or a valid locale identifier. The default locale is 'en_GB' by default, but can be set with the DefaultLocale method.
