----------The most straightforward way to parse dates with **dateparser** is to
use the ``dateparser.parse()`` function, that wraps around most of the
functionality of the module... code:: python
>>> import dateparser
>>> dateparser.parse('Fri, 12 Dec 2014 10:55:50')
datetime.datetime(2014, 12, 12, 10, 55, 50)>>> dateparser.parse('1991-05-17')
datetime.datetime(1991, 5, 17, 0, 0)>>> dateparser.parse('In two months') # today is 1st Aug 2020
datetime.datetime(2020, 10, 1, 11, 12, 27, 764201)>>> dateparser.parse('1484823450') # timestamp
datetime.datetime(2017, 1, 19, 10, 57, 30)>>> dateparser.parse('January 12, 2012 10:00 PM EST')
datetime.datetime(2012, 1, 12, 22, 0, tzinfo=)As you can see, **dateparser** works with different date formats, but it
can also be used directly with strings in different languages:.. code:: python
>>> 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)>>> dateparser.parse('yaklaşık 23 saat önce') # Turkish (23 hours ago), current time: 12:46
datetime.datetime(2019, 9, 7, 13, 46)>>> dateparser.parse('2小时前') # Chinese (2 hours ago), current time: 22:30
datetime.datetime(2018, 5, 31, 20, 30)You can control multiple behaviors by using the ``settings`` parameter:
.. code:: python
>>> dateparser.parse('2014-10-12', settings={'DATE_ORDER': 'YMD'})
datetime.datetime(2014, 10, 12, 0, 0)>>> dateparser.parse('2014-10-12', settings={'DATE_ORDER': 'YDM'})
datetime.datetime(2014, 12, 10, 0, 0)>>> dateparser.parse('1 year', settings={'PREFER_DATES_FROM': 'future'}) # Today is 2020-09-23
datetime.datetime(2021, 9, 23, 0, 0)>>> dateparser.parse('tomorrow', settings={'RELATIVE_BASE': datetime.datetime(1992, 1, 1)})
datetime.datetime(1992, 1, 2, 0, 0)To see more examples on how to use the ``settings``, check the `settings
section `__
in the docs.False positives
^^^^^^^^^^^^^^^**dateparser** will do its best to return a date, dealing with multiple formats and different locales.
For that reason it is important that the input is a valid date, otherwise it could return false positives.To reduce the possibility of receiving false positives, make sure that:
- The input string is a valid date and doesn't contain any other words or numbers.
- If you know the language or languages beforehand, you add them through the ``languages`` or ``locales`` properties.On the other hand, if you want to exclude any of the default parsers
(``timestamp``, ``relative-time``...) or change the order in which they
are executed, you can do so through the
`settings PARSERS `_.Installation
------------Dateparser supports Python >= 3.9. You can install it by doing:
::
$ pip install dateparser
If you want to use the jalali or hijri calendar, you need to install the
``calendars`` extra:::
$ pip install dateparser[calendars]
Common use cases
----------------**dateparser** can be used for a wide variety of purposes,
but it stands out when it comes to:Consuming data from different sources:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^- **Scraping**: extract dates from different places with several
different formats and languages
- **IoT**: consuming data coming from different sources with different
date formats
- **Tooling**: consuming dates from different logs / sources
- **Format transformations**: when transforming dates coming from
different files (PDF, CSV, etc.) to other formats (database, etc).Offering natural interaction with users:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^- **Tooling and CLI**: allow users to write “3 days ago” to retrieve
information.
- **Search engine**: allow people to search by date in an easy /
natural format.
- **Bots**: allow users to interact with a bot easilyYou may also like...
