Hello,
Yes, it’s possible to change the language, here’s an example:
Let’s say you want to change the language of the date picker to Spanish:
1) Add the locale file in the HTML

2) Change the options:

To change the format, you can just set it like this:
<input type="text" data-plugin-datepicker data-plugin-options='{"format": "yy/mm/dd"}' class="form-control">
Or change the default settings:
(js/custom.js)
$.extend(theme.PluginDatePicker.defaults, {
format: "yy/mm/dd"
});
Available Options:
