Matplotlib provides sophisticated date plotting capabilities, standing
on the shoulders of python datetime, the add-on modules pytz and
dateutils.  datetime objects are converted to floating point numbers
which represent the number of days since 0001-01-01 UTC.  The helper
functions date2num, num2date and drange are used to facilitate easy
conversion to and from datetime and numeric ranges.

A wide range of specific and general purpose date tick locators and
formatters are provided in this module.  See matplotlib.tickers for
general information on tick locators and formatters.  These are
described below.

All the matplotlib date converters, tickers and formatters are
timezone aware, and the default timezone is given by the timezone
parameter in your matplotlibrc file.  If you leave out a tz timezone
instance, the default from your rc file will be assumed.  If you want
to use a custom time zone, pass a pytz.timezone instance
with the tz keyword argument to num2date, plot_date, and any custom
date tickers or locators you create.  See http://pytz.sourceforge.net
for information on pytz and timezone handling.

The dateutil module (http://labix.org/python-dateutil)
provides additional code to handle
date ticking, making it easy to place ticks on any kinds of dates -
see examples below.

Date tickers -

  Most of the date tickers can locate single or multiple values.  Eg

    # tick on mondays every week
    loc = WeekdayLocator(byweekday=MO, tz=tz)

    # tick on mondays and saturdays
    loc = WeekdayLocator(byweekday=(MO, SA))

  In addition, most of the constructors take an interval argument.

    # tick on mondays every second week
    loc = WeekdayLocator(byweekday=MO, interval=2)

  The rrule locator allows completely general date ticking

    # tick every 5th easter
    rule = rrulewrapper(YEARLY, byeaster=1, interval=5)
    loc = RRuleLocator(rule)

  Here are all the date tickers

    * MinuteLocator  - locate minutes

    * HourLocator    - locate hours

    * DayLocator     - locate specifed days of the month

    * WeekdayLocator - Locate days of the week, eg MO, TU

    * MonthLocator   - locate months, eg 7 for july

    * YearLocator    - locate years that are multiples of base

    * RRuleLocator - locate using a matplotlib.dates.rrulewrapper.
        The rrulewrapper is a simple wrapper around a dateutils.rrule
        https://moin.conectiva.com.br/DateUtil which allow almost
        arbitrary date tick specifications.  See
        examples/date_demo_rrule.py


Date formatters

  DateFormatter - use strftime format strings

  DateIndexFormatter - date plots with implicit x indexing.
