In addition to Purim and it’s mitzvot, there are other mitzvot associated with Adar including the obligation to read the four parshiyot (Shekalim, Zachor, Parah, HaChodesh), Taanit Esther, and the custom of giving machatzit hashekel.
Are women obligated in the four parshiyot?
Why do we fast on Taanit Esther?
