Where a period is expressed in days, the day of the act, event, decision or notification that causes it to run shall not count.
Where a period is expressed in months or years, the period shall expire on the day of the last month or year that bears the same number as the day of the act, event, decision or notification that causes the period to run. If there is no identical date, the period expires on the last day of the month.
When a period is expressed in months and days, the months are counted first and then the days.
Any time limit expires on the last day at twenty-four hours.
A time limit that would normally expire on a Saturday, Sunday or public or bank holiday is extended until the next working day.
