The answer is: Annually

Lev 16:29-34 - The Day of Atonement was the holiest day of the year for Israel.

The Day of Atonement, or Yom Kippur, is indeed an annual event that carries deep significance in the Israelite tradition. This day wasn’t just any celebration, it marked a pivotal moment in the Jewish calendar, a time for deep introspection, repentance, and renewal. It's fascinating to note that the practices surrounding Yom Kippur still resonate today, with modern observance including fasting, prayer, and community rituals that reflect a profound yearning for—if even temporarily—atoning for one's sins.

Leviticus outlines the rituals involved, such as the scapegoat, which was an intriguing symbol of transferring the community's sins onto an innocent creature, meant to carry those sins far away. The act reflects an older literary trope commonly called "the transfer of guilt," perhaps even echoing similar traditions found in neighboring cultures of the ancient Near East.

While the observance involves solemnity, there's also a vibrant aspect of community connection. Jews come together, sharing their concerns and hopes in a powerful collective experience. Fun fact: in the Torah, the Israelites are commanded to "afflict their souls," often interpreted as engaging in acts of humility and spiritual reflection—definitely a brush with the rich tapestry of human struggle and growth.

An annual reminder like this can inspire people today to take moments in their lives for mindfulness and personal reflection, aligning with a broader sense of community values and seeking personal clarity. Such ancient traditions continue to influence and inspire people, making them timeless.
