Date format in Yii translatable applications

gistfile1.txt

// In languages key value for example app_es.php
    'yyyy-mm-dd' => 'dd/mm/yyyy',
    'Y-m-d' => 'd/m/Y',



//In controller:

        $date = DateTime::createFromFormat(Yii::t('app', 'Y-m-d') , $this->date);
        $this->date = $date->format('Y-m-d'); 



//Javascript to make datepicker (remember to ensure to be added datepicker.js and .css)

<script>
    $(document).ready(function (){
        $("#MoneyInOut_date").datepicker({
            format: '<?php echo Yii::t('app','yyyy-mm-dd') ?>',
        })
    });
</script>
