"Machzor" is a Hebrew term meaning "cycle" or "cycle of readings," specifically referring to the cycle of Jewish festivals and holy days. There are several synonyms that can be used to describe this concept, including "calendar," "ritual cycle," "liturgical year," and "seasonal cycle." Each of these terms captures the idea of a repeating, cyclical pattern of observances and celebrations, often tied to the natural rhythms of the calendar year. Additionally, some may refer to the machzor as a specific prayer book used during the High Holy Days or other Jewish festivals, in which case synonyms might include "prayer book," "service book," or "holy day liturgy".
