What is an anniversary calculator?
An anniversary calculator helps users determine how long they have been married or in a relationship by calculating the time elapsed between their wedding date and the current date. Unlike a countdown or reminder tool, an anniversary calculator automatically updates in real-time, displaying the number of years, months, days, hours, minutes, and seconds since the marriage took place.
History of wedding anniversaries
The tradition of celebrating wedding anniversaries dates back centuries. Its documented roots stem from Medieval Germany, where a husband would present his wife with a silver wreath on their 25th anniversary (the Silberhochzeit) and a gold wreath on their 50th (Goldene Hochzeit). This tradition spread across Europe and eventually to the rest of the world.
In the Victorian era (1800s England), romanticism reshaped marriage’s cultural portrayal. Anniversaries became moments to celebrate love matches and companionship rather than mere longevity. Publications like The Farmer’s Almanac (1859) formalized the idea of anniversary gifts — listing “paper” for the first year and “wood” for the fifth.
By the 20th century, thanks to commercialization and the influence of companies like Hallmark and the American National Retail Jewelers Association, an expanded list of yearly gifts was created, linking each year of marriage to specific materials and gemstones.
Today, these traditions are observed worldwide with regional variations. Below, we explore them across several countries.
