Introduction to dateparser
==========================


Features
========

* Generic parsing of dates in over 200 language locales plus numerous formats in a language agnostic fashion.
* Generic parsing of relative dates like: ``'1 min ago'``, ``'2 weeks ago'``, ``'3 months, 1 week and 1 day ago'``, ``'in 2 days'``, ``'tomorrow'``.
* Generic parsing of dates with time zones abbreviations or UTC offsets like: ``'August 14, 2015 EST'``, ``'July 4, 2013 PST'``, ``'21 July 2013 10:15 pm +0500'``.
* Date lookup in longer texts.
* Support for non-Gregorian calendar systems. See `Supported Calendars`_.
* Extensive test coverage.


Basic Usage
===========

The most straightforward way is to use the `dateparser.parse <#dateparser.parse>`_ function,
that wraps around most of the functionality in the module.

Popular Formats
---------------

    >>> import dateparser
    >>> dateparser.parse('12/12/12')
    datetime.datetime(2012, 12, 12, 0, 0)
    >>> dateparser.parse('Fri, 12 Dec 2014 10:55:50')
    datetime.datetime(2014, 12, 12, 10, 55, 50)
    >>> dateparser.parse('Martes 21 de Octubre de 2014')  # Spanish (Tuesday 21 October 2014)
    datetime.datetime(2014, 10, 21, 0, 0)
    >>> dateparser.parse('Le 11 Décembre 2014 à 09:00')  # French (11 December 2014 at 09:00)
    datetime.datetime(2014, 12, 11, 9, 0)
    >>> dateparser.parse('13 января 2015 г. в 13:34')  # Russian (13 January 2015 at 13:34)
    datetime.datetime(2015, 1, 13, 13, 34)
    >>> dateparser.parse('1 เดือนตุลาคม 2005, 1:00 AM')  # Thai (1 October 2005, 1:00 AM)
    datetime.datetime(2005, 10, 1, 1, 0)

This will try to parse a date from the given string, attempting to
detect the language each time.

You can specify the language(s), if known, using ``languages`` argument. In this case, given languages are used and language detection is skipped:

    >>> dateparser.parse('2015, Ago 15, 1:08 pm', languages=['pt', 'es'])
    datetime.datetime(2015, 8, 15, 13, 8)

If you know the possible formats of the dates, you can
use the ``date_formats`` argument:

    >>> dateparser.parse('22 Décembre 2010', date_formats=['%d %B %Y'])
    datetime.datetime(2010, 12, 22, 0, 0)


Relative Dates
--------------

    >>> parse('1 hour ago')
    datetime.datetime(2015, 5, 31, 23, 0)
    >>> parse('Il ya 2 heures')  # French (2 hours ago)
    datetime.datetime(2015, 5, 31, 22, 0)
    >>> parse('1 anno 2 mesi')  # Italian (1 year 2 months)
    datetime.datetime(2014, 4, 1, 0, 0)
    >>> parse('yaklaşık 23 saat önce')  # Turkish (23 hours ago)
    datetime.datetime(2015, 5, 31, 1, 0)
    >>> parse('Hace una semana')  # Spanish (a week ago)
    datetime.datetime(2015, 5, 25, 0, 0)
    >>> parse('2小时前')  # Chinese (2 hours ago)
    datetime.datetime(2015, 5, 31, 22, 0)

.. note:: Testing above code might return different values for you depending on your environment's current date and time.

.. note:: For `Finnish` language, please specify ``settings={'SKIP_TOKENS': []}`` to correctly parse relative dates.

OOTB Language Based Date Order Preference
-----------------------------------------

   >>> # parsing ambiguous date
   >>> parse('02-03-2016')  # assumes english language, uses MDY date order
   datetime.datetime(2016, 2, 3, 0, 0)
   >>> parse('le 02-03-2016')  # detects french, uses DMY date order
   datetime.datetime(2016, 3, 2, 0, 0)

.. note:: Ordering is not locale based, that's why do not expect `DMY` order for UK/Australia English. You can specify date order in that case as follows using `settings`:

    >>> parse('18-12-15 06:00', settings={'DATE_ORDER': 'DMY'})
    datetime.datetime(2015, 12, 18, 6, 0)

For more on date order, please look at `settings`.


Timezone and UTC Offset
-----------------------

By default, `dateparser` returns tzaware `datetime` if timezone is present in date string. Otherwise, it returns a naive `datetime` object.

    >>> parse('January 12, 2012 10:00 PM EST')
    datetime.datetime(2012, 1, 12, 22, 0, tzinfo=<StaticTzInfo 'EST'>)

    >>> parse('January 12, 2012 10:00 PM -0500')
    datetime.datetime(2012, 1, 12, 22, 0, tzinfo=<StaticTzInfo 'UTC\-05:00'>)

    >>> parse('2 hours ago EST')
    datetime.datetime(2017, 3, 10, 15, 55, 39, 579667, tzinfo=<StaticTzInfo 'EST'>)

    >>> parse('2 hours ago -0500')
    datetime.datetime(2017, 3, 10, 15, 59, 30, 193431, tzinfo=<StaticTzInfo 'UTC\-05:00'>)

 If date has no timezone name/abbreviation or offset, you can specify it using `TIMEZONE` setting.

    >>> parse('January 12, 2012 10:00 PM', settings={'TIMEZONE': 'US/Eastern'})
    datetime.datetime(2012, 1, 12, 22, 0)

    >>> parse('January 12, 2012 10:00 PM', settings={'TIMEZONE': '+0500'})
    datetime.datetime(2012, 1, 12, 22, 0)

``TIMEZONE`` option may not be useful alone as it only attaches given timezone to
resultant ``datetime`` object. But can be useful in cases where you want conversions from and to different
timezones or when simply want a tzaware date with given timezone info attached.

    >>> parse('January 12, 2012 10:00 PM', settings={'TIMEZONE': 'US/Eastern', 'RETURN_AS_TIMEZONE_AWARE': True})
    datetime.datetime(2012, 1, 12, 22, 0, tzinfo=<DstTzInfo 'US/Eastern' EST-1 day, 19:00:00 STD>)


    >>> parse('10:00 am', settings={'TIMEZONE': 'EST', 'TO_TIMEZONE': 'EDT'})
    datetime.datetime(2016, 9, 25, 11, 0)

Some more use cases for conversion of timezones.

    >>> parse('10:00 am EST', settings={'TO_TIMEZONE': 'EDT'})  # date string has timezone info
    datetime.datetime(2017, 3, 12, 11, 0, tzinfo=<StaticTzInfo 'EDT'>)

    >>> parse('now EST', settings={'TO_TIMEZONE': 'UTC'})  # relative dates
    datetime.datetime(2017, 3, 10, 23, 24, 47, 371823, tzinfo=<StaticTzInfo 'UTC'>)

In case, no timezone is present in date string or defined in `settings`. You can still
return tzaware ``datetime``. It is especially useful in case of relative dates when uncertain
what timezone is relative base.

    >>> parse('2 minutes ago', settings={'RETURN_AS_TIMEZONE_AWARE': True})
    datetime.datetime(2017, 3, 11, 4, 25, 24, 152670, tzinfo=<DstTzInfo 'Asia/Karachi' PKT+5:00:00 STD>)

In case, you want to compute relative dates in UTC instead of default system's local timezone, you can use `TIMEZONE` setting.

    >>> parse('4 minutes ago', settings={'TIMEZONE': 'UTC'})
    datetime.datetime(2017, 3, 10, 23, 27, 59, 647248, tzinfo=<StaticTzInfo 'UTC'>)

.. note:: In case, when timezone is present both in string and also specified using `settings`, string is parsed into tzaware representation and then converted to timezone specified in `settings`.

   >>> parse('10:40 pm PKT', settings={'TIMEZONE': 'UTC'})
   datetime.datetime(2017, 3, 12, 17, 40, tzinfo=<StaticTzInfo 'UTC'>)

   >>> parse('20 mins ago EST', settings={'TIMEZONE': 'UTC'})
   datetime.datetime(2017, 3, 12, 21, 16, 0, 885091, tzinfo=<StaticTzInfo 'UTC'>)

For more on timezones, please look at `settings`.


Incomplete Dates
----------------

    >>> from dateparser import parse
    >>> parse('December 2015')  # default behavior
    datetime.datetime(2015, 12, 16, 0, 0)
    >>> parse('December 2015', settings={'PREFER_DAY_OF_MONTH': 'last'})
    datetime.datetime(2015, 12, 31, 0, 0)
    >>> parse('December 2015', settings={'PREFER_DAY_OF_MONTH': 'first'})
    datetime.datetime(2015, 12, 1, 0, 0)

    >>> parse('March')
    datetime.datetime(2015, 3, 16, 0, 0)
    >>> parse('March', settings={'PREFER_DATES_FROM': 'future'})
    datetime.datetime(2016, 3, 16, 0, 0)
    >>> # parsing with preference set for 'past'
    >>> parse('August', settings={'PREFER_DATES_FROM': 'past'})
    datetime.datetime(2015, 8, 15, 0, 0)

    >>> import dateparser
    >>> dateparser.parse("2015") # default behavior
    datetime.datetime(2015, 3, 27, 0, 0)
    >>> dateparser.parse("2015", settings={"PREFER_MONTH_OF_YEAR": "last"})
    datetime.datetime(2015, 12, 27, 0, 0)
    >>> dateparser.parse("2015", settings={"PREFER_MONTH_OF_YEAR": "first"})
    datetime.datetime(2015, 1, 27, 0, 0)
    >>> dateparser.parse("2015", settings={"PREFER_MONTH_OF_YEAR": "current"})
    datetime.datetime(2015, 3, 27, 0, 0)

You can also ignore parsing incomplete dates altogether by setting `STRICT_PARSING` flag as follows:

    >>> parse('December 2015', settings={'STRICT_PARSING': True})
    None

For more on handling incomplete dates, please look at `settings`.


Search for Dates in Longer Chunks of Text
-----------------------------------------

.. warning:: Support for searching dates is really limited and needs a lot of improvement, we look forward to community's contribution to get better on that part. See "`contributing`".


You can extract dates from longer strings of text. They are returned as list of tuples with text chunk containing the date and parsed datetime object.

Time Span Detection
-------------------

The `search_dates` function can detect time spans from expressions like "past month", "last week", etc. When `RETURN_TIME_SPAN` is enabled, it returns start and end dates for the detected period.

.. code-block:: python

    >>> search_dates("Messages from the past month", settings={'RETURN_TIME_SPAN': True})
    [('past month (start)', datetime.datetime(2024, 11, 7, 0, 0)), 
     ('past month (end)', datetime.datetime(2024, 12, 7, 23, 59, 59, 999999))]

Advanced Usage
==============
If you need more control over what is being parser check the `settings` section as well as the `using-datedataparser` section.


Dependencies
============

`dateparser` relies on following libraries in some ways:

  * dateutil_'s module ``relativedelta`` for its freshness parser.
  * convertdate_ to convert *Jalali* dates to *Gregorian*.
  * hijridate_ to convert *Hijri* dates to *Gregorian*.
  * tzlocal_ to reliably get local timezone.
  * ruamel.yaml_ (optional) for operations on language files.

.. _dateutil: https://pypi.python.org/pypi/python-dateutil
.. _convertdate: https://pypi.python.org/pypi/convertdate
.. _hijridate: https://pypi.python.org/pypi/hijridate
.. _tzlocal: https://pypi.python.org/pypi/tzlocal
.. _ruamel.yaml: https://pypi.python.org/pypi/ruamel.yaml

Supported languages and locales
===============================
You can check the supported locales by visiting the "`supported-locales`" section.


Supported Calendars
===================

Apart from the Georgian calendar, `dateparser` supports the `Persian Jalali calendar` and the `Hijri/Islami calendar`

To be able to use them you need to install the `calendar` extra by typing:

    pip install dateparser[calendars]


* Example using the `Persian Jalali calendar`. For more information, refer to `Persian Jalali Calendar <https://en.wikipedia.org/wiki/Iranian_calendars#Zoroastrian_calendar>`_.

    >>> from dateparser.calendars.jalali import JalaliCalendar
    >>> JalaliCalendar('جمعه سی ام اسفند ۱۳۸۷').get_date()
    DateData(date_obj=datetime.datetime(2009, 3, 20, 0, 0), period='day', locale=None)


* Example using the `Hijri/Islamic Calendar`. For more information, refer to `Hijri Calendar <https://en.wikipedia.org/wiki/Islamic_calendar>`_.

    >>> from dateparser.calendars.hijri import HijriCalendar
    >>> HijriCalendar('17-01-1437 هـ 08:30 مساءً').get_date()
    DateData(date_obj=datetime.datetime(2015, 10, 30, 20, 30), period='day', locale=None)

.. note:: `HijriCalendar` only works with Python ≥ 3.7.

0.7.0 (2018-02-08)
------------------

Features added during Google Summer of Code 2017:

* Harvesting language data from Unicode CLDR database (https://github.com/unicode-cldr/cldr-json), which includes over 200 locales (#321) - authored by Sarthak Maddan.
  See full currently supported locale list in README.
* Extracting dates from longer strings of text (#324) - authored by Elena Zakharova.
  Special thanks for their awesome contributions!


New features:

* Added (independently from CLDR) Georgian (#308) and Swedish (#305)

Improvements:

* Improved support of Chinese (#359), Thai (#345), French (#301, #304), Russian (#302)
* Removed ruamel.yaml from dependencies (#374). This should reduce the number of installation issues and improve performance as the result of moving away from YAML as basic data storage format.
  Note that YAML is still used as format for support language files.
* Improved performance through using pre-compiling frequent regexes and lazy loading of data (#293, #294, #295, #315)
* Extended tests (#316, #317, #318, #323)
* Updated nose_parameterized to its current package, parameterized (#381)
