Blessed events are special occasions that are celebrated and often seen as a sign of good fortune. The term can refer to a variety of different events, such as sneezes, births, and new arrivals. Sneezes are the involuntary expulsion of air from the nose and mouth, usually due to an irritation in the nasal passages. Births are the process of bringing a baby into the world, and new arrivals refer to the welcoming of a new person or thing into a particular place.
