  • the sign - (minus) indicates that the division from 1418 by 33 left a fraction, which must be taken away from 1997. This means that the year 1418 of the hijra corresponds to 1996-1997. Gregorian calendar.

L'invention permet d'améliorer la précision et la fiabilité du dispositif, de simplifier et de rendre plus économique sa fabrication, et ce grâce à la présence, sur le cadran des dates, de chiffres disposés en séquence ou de marques de dates correspondant au mois lunaire musulman pair, de 1 à 29, et de chiffres disposés en séquence ou de marques de dates correspondant au mois lunaire musulman impair, de 1 à 30. Le cadran des dates se présente comme un cercle avec deux secteurs dont l'un contient les chiffres ou les marques de dates correspondant au mois lunaire musulman pair, de 1 à 29, et l'autre contient les chiffres ou les marques de dates correspondant au mois lunaire musulman impair, de 1 à 30, répartis à intervalles réguliers en suivant la le cercle. Le cadran des dates peut être disposé fixe ou mobile ou sur un disque rotatif. Le moyen d'affichage peut aussi être réalisé sous la forme d'un indicateur à aiguille ou sous la forme d'une fenêtre du cadran.
