Moed Katan is the eleventh tractate in Seder Moed. It deals mostly with the laws of Chol HaMoed – the intermediate days of Succos and Pesach. The categories of permitted melachos for Chol HaMoed are listed in Mishnah Brurah 530:1. You can use the mnemonic “Dr. Moed – המרפא” to remember them:
- ה – Maaseh Hediot: Simple unskilled labour
- מ – Tzarchei Moed: To provide for the needs of holiday joy (i.e. eating)
- ר – Tzarchei Rabbim: To provide for the needs of a rabim
- פ – Poel SheEin Lo Ma Yochal (Parnassah): One who must work to eat may do so
- א – Davar HaAveid: To prevent a loss
Chapter One: Mashkin Beis HaShlachin
The first half of chapter one deals with agriculture on Chol HaMoed with digressions into whether or not a court can overturn the ruling of a previous court and why tombs must be marked. The second half presents more laws of tombs, several aggados about Solomon and paternal blessings, and which melachos are permitted on Chol HaMoed.
Chapter Two: Mi SheHophach
The second chapter discusses shinui maaseh in melachos and whether or not fines are inherited to the heirs.
Chapter Three: VeElu Megalchin
The final chapter deals with mourning, powers of the court, bans and excommunication, mourning and chol hamoed, eulogies and funerals.
