## What is an Anniversary?

An anniversary is a date that marks a significant event or milestone that occurred in a previous year, and is traditionally celebrated or acknowledged each year on the same date. The term is most commonly used to denote the years since the occurrence of a wedding or the beginning of a romantic relationship, but it can also be used to commemorate other significant events such as the founding of a company, the end of a war, or the death of a loved one.

Anniversaries are often celebrated with special activities, gifts, or rituals that reflect the importance of the event and the passage of time. For example, wedding anniversaries are often associated with specific gifts like paper for the first year, silver for the 25th year, and gold for the 50th year.
