Astral also comes with a geocoder containing a local database that allows you
to look up information for a small set of locations (`new locations can be
added <additional_locations_>`__).

Note on Localized Timezones
===========================

When creating a datetime object in a specific timezone do not use the
`tzinfo` parameter to the datetime constructor. Instead use the
:meth:`~pytz.tzinfo.localize` method provided by pytz on the correct pytz

Version Description
========== ====================================================================
3.0 Added moon rise, set, azimuth and zenith functions.

Switched from pytz to `zoneinfo` provided as part of Python >= 3.9 or
`backports.zoneinfo` for older versions.

In some circumstances the result of the calculation of rise and
set times would return information for a diffrerent date. This
has now been fixed.

2.2 Fix for `bug #48`_ - As per the bug report the angle to adjust for
the effect of elevation should have been θ (not α).
