The answer is: Celebrate the Feast of Trumpets

Lev 23:24 - The Feast of Trumpets marked the beginning of the civil new year.

The Feast of Trumpets, also known as Rosh Hashanah in Jewish tradition, is a fascinating event rooted in the ancient practices of the Israelites. Celebrated on the first day of the seventh month, it held significant importance not just as marking the new civil year but also ushering in a time of reflection, repentance, and spiritual renewal. Sounding the trumpets, or shofars, signified the call to awaken the faithful and focus on self-examination and repentance.

Interestingly, the shofar made from the horn of a ram or other animal is not just a musical instrument. Its sound carries profound symbolism, representing calls for vigilance and reminding people of their covenant with their Creator. It's intriguing to note how trumpets were also used in ancient Israel to announce not just festivals but also to call warriors to battle. This dual purpose of the trumpet showcases its role in both celebration and awakening—to awaken one's spirit spiritually as well as prepare for physical challenges.

Furthermore, this festival's relation to other significant Biblical dates adds depth. Just ten days following the Feast of Trumpets is Yom Kippur, the Day of Atonement, amplifying the themes of remorse and reconciliation with one another and with God. This importance underscores not only the Israelites' adherence to divine commandments, but encourages all to consider res branding and personal growth as cycles of life progress, just like the changing of a year. What delightful connections we find in scripture!
