The WEEKS() function returns the difference between two dates in weeks. The third parameter indicates the calculation mode: if the mode is 0, WEEKS() returns the maximal possible number of weeks between those days. If the mode is 1, it only returns the number of whole weeks in between.
De funksje WIKEN () berekkent it ferskil tusken de twa data yn wiken. De tredde parameter bepaalt de berekkeningsmetoade. As de metoade 0 is, dan jout WIKEN () it grutst mooglike oantal wiken werom tusken dizze dagen. As de metoade 1 is, dan jout it allinnich it oantal hiele wiken werom tusken dizze dagen.
