ויקרא, פרק כ״ג, פסוק א׳

The sacred calendar of the Israelites represents a profound shift from the physical to the temporal. While earlier instructions focused on creating holiness in a specific place, such as the Tabernacle, the focus now turns to creating holiness in time. Establishing sacred times is the ultimate symbol of freedom. A free person has mastery over their own schedule, whereas a slave's time belongs entirely to their master [רש ר הירש].

The primary approach among commentators is that the Hebrew calendar does not operate automatically based on natural cycles. Instead, God places the responsibility of establishing these appointed times directly into the hands of the rabbinic court. The determination of when a festival occurs depends entirely on the court's declaration. So absolute is this authority that even if the judges make an error—whether by accident or on purpose—their ruling remains valid and binding [מלבי״ם]. Entrusting this power to human leadership serves to unite the nation, preventing a chaotic situation where every individual sets their own holiday schedule [אברבנאל]. It also allows for practical flexibility; the court can delay a festival to accommodate the needs of the people, such as waiting for pilgrims who are still traveling [מלבי״ם].

By officially declaring these days, the court essentially creates a new reality. They take an ordinary weekday and infuse it with the profound sanctity and identity of a festival [מלבי״ם]. Yet, despite this deep human involvement, these appointed times remain God's festivals. They are not merely national holidays, but specific moments when God actively leads and judges the world [העמק דבר]. The requirement to declare them as holy occasions means honoring the day through eating, drinking, prayer, and public gathering [העמק דבר]. Furthermore, these declarations serve as an invitation, drawing spiritual abundance down from the highest realms of holiness into the physical world [אלשיך].

Directly following this introduction to the calendar, the Sabbath is introduced. The primary approach among commentators is that the Sabbath is mentioned here specifically to highlight the contrast between it and the other festivals. The holiness of the Sabbath is entirely divine, permanent, and independent, having been established at the very beginning of creation. In contrast, the holiness of the festivals relies on human declaration. This fundamental distinction explains the difference in their laws: preparing food is strictly forbidden on the Sabbath, yet it is permitted on the festivals [אברבנאל, אלשיך]. Alternatively, the inclusion of the Sabbath serves as a practical legal instruction. It teaches that when a festival happens to fall on the Sabbath, the stricter laws of the Sabbath take precedence, meaning food preparation remains prohibited. Following this brief clarification, the narrative simply restarts the introduction to the festivals to continue the list [רד צ הופמן].

The laws of the festivals are recorded three separate times throughout the Torah, with each instance serving a distinct purpose. Here in Leviticus, the primary focus is on the calendar itself and the specific dates. Later, in the book of Numbers, the focus shifts to the detailed requirements of the sacrifices, which are only briefly hinted at here. Finally, in the book of Deuteronomy, the emphasis is placed on the physical pilgrimage and the public instruction of the people [רש ר הירש, רד צ הופמן].
