The answer is: Purim

Esther 9:26

Purim is a vibrant celebration that the Jewish community has enjoyed for centuries, commemorating the survival of the Jews who were marked for destruction in ancient Persia, as recorded in the Book of Esther. What makes this festival so fascinating is not only its spirited nature—complete with costumes, revelry, and festive meals—but also its origin as a direct response to a crisis of survival. The story culminates with Queen Esther bravely revealing her Jewish identity and exposing the malicious plan of Haman, making Her Michael Catt's quote come alive: "You might find out who you are by bringing out the truth of good and evil, not just saving people."

Turning this event into a festival was more than a historical marking; it set a precedent for themes of resistance, survival, and communal joy. Since Esther's time, Purim has become a reflected beacon of hope, nurturing the strength of identity amid adversity. Traditionally, people read the Book of Esther during Purim and use groggers, or noise-makers, to drown out Haman’s name—a cheeky way to make "waves" against an antagonist!

It's interesting to note that this celebration takes place on the 14th of Adar, creating an annual reminder of the resilience portrayed in Esther's story, and drawing echoes from other biblical events, such as the Exodus, which reminds one of liberation. The essence of Purim extends beyond remembrance; it teaches perseverance and the joy found in community, offering a celebratory antidote to the sufferings of history.
