        "\n# Date tick labels\n\nMatplotlib date plotting is done by converting date instances into\ndays since an epoch (by default 1970-01-01T00:00:00). The\n:mod:`matplotlib.dates` module provides the converter functions `.date2num`\nand `.num2date` that convert `datetime.datetime` and `numpy.datetime64`\nobjects to and from Matplotlib's internal representation.  These data\ntypes are registered with the unit conversion mechanism described in\n:mod:`matplotlib.units`, so the conversion happens automatically for the user.\nThe registration process also sets the default tick ``locator`` and\n``formatter`` for the axis to be `~.matplotlib.dates.AutoDateLocator` and\n`~.matplotlib.dates.AutoDateFormatter`.\n\nAn alternative formatter is the `~.dates.ConciseDateFormatter`,\nused in the second ``Axes`` below (see\n:doc:`/gallery/ticks/date_concise_formatter`), which often removes the need to\nrotate the tick labels. The last ``Axes`` formats the dates manually, using\n`~.dates.DateFormatter` to format the dates using the format strings documented\nat `datetime.date.strftime`.\n"
