Creating a Holiday Hours style custom field

Hi,

Is there a way to create a holiday hours style custom field or custom field type? I have experimented with adding the date, hours and daily times field to a custom field type, but can’t quite get any to work. The date field does not include hours, the hours field is specified per day of the week and the daily times field is again specified per day of the week. In this case, we need the hours specified per date.

Is there a way to do this?

Thanks,

Ollie
