I need to display/edit time ranges on a web form. A time range includes a day and a time. So, an example range would be "Mon 9:00am" to "Tue 10:00am." I would like a solution that will let users edit a given list of ranges like this on their web browser and submit new changes. The solution should come with a simple html demo that shows it works (minus the backend support). It should have fields for starting point, the ending point, and a listbox or text field where user can add new ones, delete or modify old ones. All of this activity should be done on the client side in the web browser. There is no reason to use a JS/JQuery date package but in case you need it, please use jQuery DatePicker.
