Widget class change (open to closed)

Thank you fo the plugin. it’s working great.

I cannot figure out how to get the class to change on the main container <div> to change classes when the business is closed.

For example, when the business is fully closed for the day (mondays) the container div is classed “widget_widget_op_is_open” and the spans are classed “op-closed”

I want the div to be “widget_widget_op_is_closed” and then the span “op-closed” so I can change the colour of the backgrounds.
