Recital 41

(41)In order to ensure legal certainty, it is appropriate that Council Regulation (EEC, Euratom) No 1182/71 of 3 June 1971 determining the rules applicable to periods, dates and time limits ¹¹ should apply to the calculation of the periods contained in this Directive. Therefore, all periods contained in this Directive should be understood to be expressed in calendar days. Where a period expressed in days is to be calculated from the moment at which an event occurs or an action takes place, the day during which that event occurs or that action takes place should not be considered as falling within the period in question.
