Time zone-aware ``day``, ``month``, and ``week_day`` lookups
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Django 1.6 introduces time zone support for :lookup:`day`, :lookup:`month`,
and :lookup:`week_day` lookups when :setting:`USE_TZ` is ``True``. These
lookups were previously performed in UTC regardless of the current time zone.
This requires :ref:`time zone definitions in the database
<database-time-zone-definitions>`. If you're using SQLite, you must install
pytz_. If you're using MySQL, you must install pytz_ and load the time zone
tables with `mysql_tzinfo_to_sql`_.
