An anniversary is the yearly return of the date when something important happened. Most commonly, people celebrate wedding anniversaries to mark another year of marriage. Your parents might celebrate their tenth anniversary by going out to dinner or taking a special trip together.

People celebrate all kinds of anniversaries beyond weddings. A town might hold a celebration for the 200th anniversary of its founding. A business might mark its 25th anniversary with a special sale. Schools celebrate milestone anniversaries with reunions. Nations commemorate the anniversaries of important historical events.

Some anniversaries carry special names. A 50th wedding anniversary is called a golden anniversary, while a 100th anniversary is called a centennial.

Anniversaries remind us that time keeps moving forward, but some moments matter enough to pause and remember, year after year. They're markers that help us appreciate how far we've come and what we've built or achieved together.
