This version brings small changes and performance improvements.

New features

Support for EXIF-formatted strings in parse()

Pendulum now supports parsing EXIF datetime strings (in the form YYYY:MM:DD hh:mm:ss).

>>> import pendulum

>>> pendulum.parse('2016:12:26 15:45:28')
# <Pendulum [2016-12-26T15:45:28+00:00]>

Changes

Performance improvements when parsing ISO 8601 strings

This version adds a C extension to improve ISO 8601 string parsing performances.

Time in seconds to parse 10000 strings

Under the hood it uses the parse_iso8601() helper (only available with C extensions activated) which is the fastest and most accurate ISO 8601 datetime parser in Python. Let's take a look:

Fixes

  • Fixed parsing of ISO 8601 week dates.

    >>> import pendulum
    
    # Before
    >>> pendulum.parse('2009-W01-1')
    <Pendulum [2009-01-05T00:00:00+00:00]>
    # Wrong should be 2008-12-29
    
    >>> pendulum.parse('2009-W53-7')
    # ParserError: Invalid date string: 2009-W53-7
    
    # Now
    >>> pendulum.parse('2009-W01-1')
    <Pendulum [2008-12-29T00:00:00+00:00]>
    
    >>> pendulum.parse('2009-W53-7')
    <Pendulum [2010-01-03T00:00:00+00:00]>
    
  • Fixed eu and sk locales. (Thanks to eumiro)
