Regulation 12

A period expressed in days or months after or from the happening of an event or the doing of any act or thing excludes the day on which the event happens or the act or thing is done.

A period expressed in months ends with the expiry of whichever day in the last month is the same day of the month as the day on which the event or the act or thing after or from which the period is to be calculated happens or is done.

If, in a period expressed in months, the day on which it should expire does not occur in the last month, the period ends with the expiry of the last day of that month.

Where the time specified by the Minister or these Regulations for doing any act expires on a Saturday, Sunday or public holiday, the act is in time if done on the next following working day.
