How does this provision count time?

  2. Establish the actual filing, service, hearing or listing event from the accepted document and proof.

Rule 13.4 uses the same-numbered date for months, ending on the last day when that number does not exist. Its nonleap anniversary rule uses February 28 for a February 29 event.

Interpretation Act section 22(1) addresses expiry on a defined holiday; section 22(2) separately addresses closure of the actual required office or place. Section 28(1)(x) includes Sundays and specified holidays, but does not make every Saturday a holiday. A registry closure is not an automatic service extension. A backward minimum interval must remain satisfied. Actual proclaimed holidays, unsupported closures or an unestablished service method require separate review.
