An anniversary of a wedding is the anniversary of the wedding date. It’s common for couples to celebrate their partnership on this special day, either in secret or at a bigger gathering. It’s common practice to celebrate and offer gifts on special occasions like milestone anniversaries (such as 10, 15, 20, or 25 years). Milestone anniversaries have customary titles in some cultures. For example, fifty years of marriage can be referred to as a “golden wedding anniversary,” “golden anniversary,” or “golden wedding.”
