The answer is: Feast of Trumpets

Lev 23:24

The Feast of Trumpets, known as Rosh Hashanah in Jewish culture, marks the Jewish New Year and is celebrated on the first day of the month Tishrei, symbolizing a season of renewal and reflection. Equivalent to a cosmic reset, this day not only begins a calendar year but also kicks off the Ten Days of Repentance, leading up to Yom Kippur, the Day of Atonement. Imagine a festivity filled with the sounds of the shofar, a ram's horn, that calls people to wake up spiritually as they prepare for judgment.

Interestingly, Rosh Hashanah has rich connections not only to the past but also to agricultural cycles and the subsequent harvest festival, reminding us of our perennial bond with the earth. The blowing of the shofar plays a vital role, embodying the call to amend one's ways — perhaps similar to ancient battle calls but focused on inner reflection rather than conflict.

Echoes of transformation are prevalent in the theme of feasts throughout the Bible. Just as the Feast of Trumpets signals new beginnings, other feasts like Passover illustrate liberation and renewal of spirit. These celebrations bring communities together, emphasizing a collective journey toward understanding and growth renown in the Hebrew tradition.

So as one enjoys the festivities, they not only connect with their heritage but also with a momentous transition embraced throughout the ages—a cycle of internal checking set against the rhythmic beauty of creation itself. The beauty of these traditions continues to resonate even in today's world.
