1.9 Calculation of time
(1) If, for any purpose, these rules ¾
(a) prohibit, permit or require an act or thing to be done within, by, or before the end of; or
(b) otherwise prescribe, allow or provide for,
a period of time before or after a particular day, act or event, the period is to be calculated without counting that day, or the day of the act or event, as the case may be.
(2) Without limiting subrule (1), in calculating how many days a particular day, act or event is before or after another day, act or event, only the first day, or the day of the first act or event, is to be counted.
(3) If the last day of any period prescribed or allowed by these rules for an act or thing to be done falls on a day that is not a business day in the place where the act or thing is to be or may be done, the act or thing may be done on the first business day in the place after that day.
(4) In calculating a period of time for the purposes of these rules, the period beginning on 25 December in a year and ending at the end of 1 January in the next year is not to be counted.
