Where did you do this: "disable css and js"?
You still have a script conflict going on. Troubleshooting it is going to be difficult for us from here. However, I see several general problems which need to be resolved before calculations will work.
You are loading multiple versions of jQuery:
Both versions are old. We use the jQuery version which is included with your WordPress version. You are loading other versions and that's the reason this is not working.
You're also loading multiple jQuery UI datepicker scripts:
The wp_enqueue_script function aims to eliminate these conflicts. Gravity Forms enqueues its scripts. It's possible your theme or some other plugins are hard-coding their scripts. In any event, you need to remove all these conflicting script versions and let WordPress enqueue the proper version of jQuery. At that point, your form calculations will work.
