I installed on the page with the help of yii2 a field into which the date is inserted (via the DatePicker ), but there are problems:
1. Date is not formatted.
2. Year 2021 is displayed.

<?php $form = ActiveForm::begin(); ?> <?= $form->field($model, 'startDate')->widget(yii\jui\DatePicker::className(), ['clientOptions' => ['defaultDate' => '2016-04-01', 'dateFormat' => 'yy-mm-dd']]) ?> <?= $form->field($model, 'lastDate')->widget(yii\jui\DatePicker::className(), ['clientOptions' => ['defaultDate' => '2016-05-01', 'dateFormat' => 'yy-mm-dd']]) ?> <div class="form-group"> <?= Html::submitButton('Отправить', ['class' => 'btn btn-primary']) ?> </div> <?php ActiveForm::end(); ?>

    I do not know why, but when I made the changes in the code, the errors were decided.

      <?= $form->field($model, 'startDate')->widget(yii\jui\DatePicker::className(), [ 'dateFormat' => 'yyyy-MM-dd' ] ) ?> <?= $form->field($model, 'lastDate')->widget(yii\jui\DatePicker::className(), [ 'dateFormat' => 'yyyy-MM-dd' ] ) ?>
