The Four Parshiot

"The four parshiot" refers to four unique Torah selections that are read in synagogues, after the regular weekly Torah portion, before and throughout the Hebrew month of Adar. The four parshiot are: shekalim, read on the Shabbat before the month of Adar, zakhor, read on the Shabbat before the holiday of Purim, parah, generally read on the Shabbat after Purim, and hachodesh, read on the Shabbat before the Hebrew month of Nisan.
