Business Open and Close hours for each day of the week - how best to structure in the database using ASP and javascript

I'll be using this code for a timepicker so businesses can select their hours of business for each day of the week:

<input name="time" value="" />
<script type="text/javascript">
    $(document).ready(function(){
        $('input[name="time"]').ptTimeSelect();
    });
</script>

Select allOpen in new window

I need to know the best way to structure this in the ClientAdverts table: i.e. how best to store the business opening and closing hours from Monday - Sunday.

Can this be done in one field? E.g. An 'OpenHours' field containing all the open and close times from Monday - Sunday for each business listing?

The the data will need to be listed separately/vertically for each day of the week, e.g:

Monday: 08.30 - 17.30
Tuesday: 08.30 - 17.30
Sunday: Closed

Etc.

Some help and suggestions would be great.
