+WeekType Field
+==============
+
+.. versionadded:: 4.4
+
+    The ``WeekType`` type was introduced in Symfony 4.4.
+
+This field type allows the user to modify data that represents a specific
+`ISO 8601`_ week number (e.g. ``1984-W05``).
+
+Can be rendered as a text input or select tags. The underlying format of
+the data can be a string or an array.
+

+Field Options
+-------------
+
+.. include:: /reference/forms/types/options/choice_translation_domain.rst.inc
+
+placeholder
+~~~~~~~~~~~
+
+**type**: ``string`` | ``array``
+
+If your widget option is set to ``choice``, then this field will be represented
+as a series of ``select`` boxes. When the placeholder value is a string,
+it will be used as the **blank value** of all select boxes::
+
+    use Symfony\Component\Form\Extension\Core\Type\WeekType;
+
+    $builder->add('startWeek', WeekType::class, [
+        'placeholder' => 'Select a value',
+    ]);
+
+Alternatively, you can use an array that configures different placeholder
+values for the year and week fields::
+
+    use Symfony\Component\Form\Extension\Core\Type\WeekType;
+
+    $builder->add('startDateTime', WeekType::class, [
+        'placeholder' => [
+            'year' => 'Year', 'week' => 'Week',
+        ]
+    ]);
+
+
+.. include:: /reference/forms/types/options/html5.rst.inc
+
+input
+~~~~~
+
+**type**: ``string`` **default**: ``array``
+
+The format of the *input* data - i.e. the format that the date is stored
+on your underlying object. Valid values are:
+
+* ``string`` (e.g. ``2011-W17``)
+* ``array`` (e.g. ``[2011, 17]``)
+
+The value that comes back from the form will also be normalized back into
+this format.
+
+widget
+~~~~~~
+
+**type**: ``string`` **default**: ``choice``
+
+The basic way in which this field should be rendered. Can be one of the
+following:
+
+* ``choice``: renders two select inputs.
+
+* ``text``: renders a two field input of type ``text`` (year, week).
+
+* ``single_text``: renders a single input of type ``week``.
+
+years
+~~~~~
+
+**type**: ``array`` **default**: ten years before to ten years after the
+current year
+
+List of years available to the year field type. This option is only relevant
+when the ``widget`` option is set to ``choice``.
+

+.. include:: /reference/forms/types/options/weeks.rst.inc
+
+Overridden Options
+------------------
+
+.. include:: /reference/forms/types/options/compound_type.rst.inc
+
+.. include:: /reference/forms/types/options/empty_data.rst.inc
+    :end-before: DEFAULT_PLACEHOLDER
+
+The actual default value of this option depends on other field options:
+
+* If ``widget`` is ``single_text``, then ``''``
+  (empty string);
+* Otherwise ``[]`` (empty array).
+
+.. include:: /reference/forms/types/options/empty_data.rst.inc
+    :start-after: DEFAULT_PLACEHOLDER
+
+error_bubbling
+~~~~~~~~~~~~~~
+
+**default**: ``false``
