(4) If one party gives notice to the other because of the other's non-performance or because such non-performance is reasonably anticipated by the first party, and the notice is properly dispatched or given, a delay or inaccuracy in the transmission of the notice or its failure to arrive does not prevent it from having effect.

(2) Official holidays and official non-working days occurring during the period are included in calculating the period. However, if the last day of the period is an official holiday or official non-working day at the address of the addressee, or at the place where a prescribed act is to be performed, the period is extended until the first following working day in that place. 54
(3) Periods of time expressed in days, weeks, months or years shall begin at 00.00 on the next day and shall end at 24.00 on the last day of the period; but any reply that has to reach the party who set the period must arrive, or other act which is to be done must be completed, by the normal close of business in the relevant place on the last day of the period.
