Why Is It Called Mar-Heshvan?

In "Why Is It Called Mar-Heshvan?", Eli Mercer undertakes a concise investigation into the origins and evolution of the name for the second month of the Jewish civil calendar. This work traces the month's various names across languages and historical periods, examining the Akkadian form often linked to *waraḥsamnu* and detailing its integration into Jewish calendrical practices. The book explores how the division of the word into the Hebrew *mar* and *Heshvan* led to new interpretations. It analyzes common explanations for the "bitter" designation, such as the absence of major festivals, seasonal rainfall, or painful historical events, framing these as later homiletic or folk etymologies rather than undisputed linguistic history. Mercer also clarifies the position of Sigd on 29 Heshvan as a distinct Beta Israel and Ethiopian Jewish observance, addressing the claim of the month being entirely without holidays.

This study also addresses alternative spellings like Heshvan and Cheshvan, explaining them through transliteration differences rather than ranking them as correct or incorrect. Examples are drawn from rabbinic usage, medieval calendars, modern Hebrew, and English-language Jewish publications to illustrate these points. A dedicated chapter discusses how an etymology, even if historically uncertain, can still hold spiritual significance when clearly presented as such. The text maintains a clear distinction between mystical readings and philological or Halakhic analysis. Accessible charts are included to assist readers in tracking consonant shifts and linguistic developments throughout the month's naming history.
