How often did Mordecai obligate the Jews to keep the fourteenth and the fifteenth day of Adar?

And he sent letters to all the Jews who were in all the provinces of the king Ahasuerus, the near ones and the far ones, 21 to set up for them to be making the fourteenth day of the month of Adar and the fifteenth day of it, every year by year.
