Father's Day is observed in Australia, New Zealand, Fiji, and Papua New Guinea on the first Sunday of September. This celebration honors fathers and father figures, allowing children to express appreciation through handmade gifts and quality time spent together. The holiday has its origins in the American Father's Day, which was introduced by Sonora Smart Dodd to honor her father, a Civil War veteran and single parent of six. Although the original date was tied to her father's death, different countries adopted their own dates for the celebration. In these regions, various events are held to recognize and celebrate fatherhood, reflecting similar customs to those found in other countries. While not a public holiday, Father's Day is widely celebrated and holds significant cultural importance.
