Rule 2.9 Computation of time
This rule shows how to calculate any period of time for doing any act which is specified—
by these rules;
by a practice direction; or
by a direction or order of the court.
A period of time expressed as a number of days must be computed as clear days.
In this rule “clear days” means that in computing the numbers of days—
the day on which the period begins; and
if the end of the period is defined by reference to an event, the day on which that event occurs,
are not included.
Where the specified period is 7 days or less and includes a day which is not a business day, that day does not count.
When the period specified—
by these rules or a practice direction; or
by any direction or order of the court,
for doing any act at the court office ends on a day on which the office is closed, that act will be in time if done on the next day on which the court office is open.
