A birthday is a special day that celebrates the anniversary of a person's birth. It is often marked with fun activities, such as parties, cake, and gifts. Many people enjoy gathering with family and friends to share joy and create lasting memories. The birthday cake is a traditional centerpiece, often decorated with candles that represent the person's age. In many cultures, birthdays are significant milestones. Some people have unique traditions, like the quinceañera for turning 15 or the sweet sixteen celebration. Regardless of how it's celebrated, a birthday is a time for reflection, gratitude, and looking forward to the year ahead.
