"Notice of an appeal under this section must be given in accordance with the Rules of Court before the end of the permitted period, which is seven days starting with the day on which the order is made."
"When the period specified by the Rules or a Practice Direction or by any judgment or court order for doing any act at the court office ends on a day on which the office is closed, that act shall be in time if done on the next day on which the court office is open."
"So I am prepared to hold that when a time is prescribed by statute for doing any act and that act can only be done if the court office is open on the day when the time expires, then if it turns out in any particular case that the day is a Sunday or other dies non, the time is extended until the next day on which the court office is open."
