Change amount based on week day

Hi dear chrono-team,
​
im using chronoforms for request form including event cost calculation:
​
Field one: Select Event (dropdown)
Field two: select wished Date and Time (datetime picker)

Let's say there is a event costs 100 € under the week but 110 € on weekend. Is it possible to calculate amount not only event depending, but also depending on week day?
​
For now im using data value on advanced tab for dropdown to calculate fix amount for each available event.
​
As next i would interested if it's possible to make open hours based on seleted day in diteimepicker. E.g.:

1. day 1-5: 10 o'clock to midnight
2. day 6-7: 8 o'clock to midnight

​
Thanks in advance
Alex

Sure, you can do anything you feel like. Something like onChange of the dropdown, call a custom function, with something like
​

function pricePerDayOfWeek() {
   var day = moment(jQuery('input[name="calendar_name"]').val()).day();
   var price = 100;
   if(day == 0 || day == 6) {
      // Day is a Saturday or Sunday
       price = 110;
   }
   jQuery('#priceDiv').html("The price will be " + price + " Euros";
}

Thanks for quick reply. I'll try asap =)
