Article 18

A period of time, calculated as a number of days, shall be computed in clear days.

“Clear days” means that, in computing the number of days, the day on which the period begins is not included and the day on which the period ends is included.

A specified period of five days or less does not include Saturdays, Sundays or legal holidays.

When the specified period for doing any act at the court office ends on a day on which the office is closed, that act shall be done in time on the next day on which the court office is open. If the period ends on a day on which weather or other conditions have made the court office inaccessible, the act shall be done in time on the first day after the inaccessibility has stopped.

Whenever a party has the right or is required to do some act within a prescribed period after the service of a notice or paper, and the notice or paper is served upon him by mail, seven days shall be added to the prescribed period.
