What Is an Anniversary? History, Meaning & Tradition
The origins of anniversary traditions, the history of anniversary names and why we celebrate
The word anniversary comes from the Latin anniversarius — from annus (year) and versus (turning), literally meaning "the yearly return of a date." Humans have marked the annual recurrence of meaningful events for thousands of years, from ancient Egyptian festivals to Roman religious calendars.
The tradition of assigning specific materials or themes to anniversary years is believed to have originated in medieval Germany, where husbands would present their wives with silver garlands for a 25th anniversary and gold garlands for a 50th anniversary. The broader list of anniversary materials was codified and popularised in the Victorian era, when Queen Victoria's own long marriage to Prince Albert made anniversary celebrations fashionable throughout Britain and its empire.
In 1937, the American National Retail Jewelers Association published an expanded and standardised list of anniversary names, adding both traditional and modern themes for years 1 through 15, and then for milestone years beyond. This is why you will find both "traditional" and "modern" themes listed for many anniversaries — the traditional themes reflecting medieval custom and the modern themes introduced in the 20th century, often featuring precious gemstones.
In modern culture, especially among younger generations, day milestones have emerged as equally meaningful celebrations. Marking 100 days, 500 days, and 1,000 days together has become popular worldwide, particularly in East Asian cultures where "100-day anniversaries" (known as baekil in Korean culture) carry significant cultural meaning and are celebrated with gifts and special dinners.
365 days: The first full year — often the most celebrated non-wedding anniversary.
500 days: Widely celebrated worldwide, especially by younger couples.
1,000 days: A major milestone — almost 3 years of shared experiences.
5,000 days: ~13.7 years — a truly exceptional milestone.
Anniversary & Relationship Facts, Statistics & Records
Fascinating facts about love, marriage, anniversaries and long-lasting relationships
The Longest Recorded Marriage
The longest verified marriage on record lasted 86 years and 290 days — between Herbert Fisher (born 1905) and Zelmyra Fisher (born 1907) of North Carolina, USA. They married on 13 May 1924 and Herbert passed away on 27 February 2011. Zelmyra passed in 2013 at age 105. Their secret? "There is no secret. We just kept our vows."
How Many Marriages Reach Their 25th Anniversary?
Only about 54% of first marriages in the United States reach the 25-year mark, according to US Census Bureau data. The chances improve significantly after the first 5 years — couples who make it to their 5th anniversary have a 70%+ chance of reaching their 25th. Second and third marriages have lower survival rates than first marriages.
Most Popular Anniversary Gift
Flowers are the most universally given anniversary gift, followed by jewellery and restaurant dinners. The US greeting card industry produces over 180 million anniversary cards per year — making it the fourth most popular card occasion after birthdays, Christmas and Valentine's Day. The global anniversary gift market is estimated at over $20 billion annually.
Anniversary Traditions Around the World
In Germany, the origin country of anniversary traditions, couples celebrating a 25th anniversary ring a decorated silver bell. In the Netherlands, a spouse who reaches their 12.5-year (copper) anniversary is said to have a "koperen bruiloft." In Japan, the 25th anniversary (銀婚式, ginkonshiki) and 50th (金婚式, kinkonshiki) are the two most formally celebrated milestones.
The Golden Anniversary: How Rare Is It?
A Golden Anniversary (50 years of marriage) is genuinely rare. Given that people typically marry in their late 20s–early 30s, celebrating 50 years together means both partners would need to be in their late 70s–early 80s. In the UK, less than 1 in 20 marriages reaches the 50-year mark. Those who do are often featured in local newspapers and may receive a congratulatory letter from the head of state.
The Diamond Anniversary: 60 or 75 Years?
There is a common confusion: the 60th anniversary is also called the Diamond Anniversary in the UK and many Commonwealth countries (following Queen Victoria's Diamond Jubilee in 1897). However, in North America, the 75th anniversary is traditionally the Diamond one, with the 60th being called the Diamond or Platinum. Queen Elizabeth II held both a Diamond Jubilee (60 years as monarch, 2012) and a Platinum Jubilee (70 years, 2022).
The Psychology of Anniversary Celebrations
Research by psychologists at the University of Virginia found that couples who regularly celebrate relationship milestones report 23% higher relationship satisfaction scores than those who don't. Celebration creates positive shared memories, reinforces commitment, and triggers the release of oxytocin (the "bonding hormone"). Even small celebrations — a card, a special dinner — have measurable positive effects on relationship quality.
The Rise of Day-Count Anniversaries
Google searches for "days since [date]" and "how long have we been together" have grown by over 300% in the past decade, reflecting the growing trend of day-count relationship tracking, particularly among Gen Z and Millennial couples. South Korean dating culture's baekil (100-day anniversary) tradition has spread globally through K-drama and K-pop influence, with the practice now common in over 30 countries.
