This module contains various exceptions used by python-chrono.

.. note::

   These exceptions are imported into the main :mod:`chrono` module,
   and can therefore be referenced both via (for example)
   :class:`chrono.error.YearError` and :class:`chrono.YearError`.

The exception tree is structured as follows:

* :class:`Exception`

  * :class:`chrono.error.NoDateTimeError`
  * :class:`ValueError`

    * :class:`chrono.error.DateTimeError`

      * :class:`chrono.error.DateError`

        * :class:`chrono.error.DayError`
        * :class:`chrono.error.MonthError`
        * :class:`chrono.error.WeekError`
        * :class:`chrono.error.YearError`

      * :class:`chrono.error.TimeError`

        * :class:`chrono.error.HourError`
        * :class:`chrono.error.MinuteError`
        * :class:`chrono.error.SecondError`

    * :class:`chrono.error.ParseError`
