Whenever a period of days for the doing of any act is provided for in the Code or in these rules, the day from which the period begins to run shall not be counted, and the last day of the period shall be counted, except where that last day is a Saturday, Sunday or a public holiday at the place of conciliation, in which case the last day shall be the next business day.

When the time provided for is less than seven days, intermediate Saturdays, Sundays and public holidays shall be excluded from the computation.
