The day emphasizes the importance of creating an inclusive, safe, environmentally sustainable, and livable urban environment amid climate change and population growth.

The event is intended to draw attention to preserving the unique marine ecosystem, combating pollution by petroleum products and plastic, protecting biodiversity, and addressing the problem of overfishing.
Halloween
A traditional holiday originating from the ancient Celtic pagan festival of Samhain, which marked the end of the harvest and the beginning of the "dark half of the year."
In modern popular culture, Halloween has become a global entertainment holiday featuring pumpkin lantern carving, costume parties, children collecting candy, and horror- and mysticism-themed events.
Reformation Day
An official public and religious holiday in many regions of Germany, Slovenia, numerous Swiss cantons, and Protestant communities around the world.
The date was established to commemorate October 31, 1517, when German theologian Martin Luther nailed his famous "95 Theses" to the door of the Castle Church in Wittenberg. This act sharply exposed the Catholic Church's abuses involving the sale of indulgences and marked the beginning of the Reformation in Europe and the emergence of Protestantism.

According to the new calendar, Orthodox and Greek Catholic believers commemorate the holy Apostles of the Seventy: Stachys, Amplias, Urbanus, Narcissus, Apelles, and Aristobulus - disciples of the Chief Apostles Peter and Paul, who ordained them as bishops and preached the Gospel in various parts of the Roman Empire.
Saint Stachys was the first bishop of Byzantium, appointed by the Apostle Andrew the First-Called, and together with his companions endured numerous hardships and tortures for the faith.
According to the old calendar, believers commemorate the holy Apostle and Evangelist Luke - one of Christ's seventy disciples, a companion of the Apostle Paul, a physician, and the author of one of the four Gospels and the Book of Acts of the Apostles. According to church tradition, Saint Luke was the first icon painter and painted the first images of the Mother of God.
