Anniversary Calculator

Enter a wedding or start date to see how many years you’ve marked, when the next anniversary falls, and the traditional gift for it.

What this calculator does

Give it the wedding date — or any start date worth marking — and it returns three things people actually look up: the years completed so far, the exact date and count of the next anniversary with a day countdown, and the traditional gift material for that milestone, from paper at the first all the way to platinum at the seventieth.

How to use it

  1. Enter the wedding or start date.
  2. Read the completed years as of today.
  3. Check the next anniversary’s date, the countdown, and its traditional gift.

The traditional list

1 paper · 5 wood · 10 tin · 25 silver · 40 ruby · 50 gold · 60 diamond · 70 platinum

A worked example

A couple married on 20 June 2015 has, as of mid-August 2026, completed 11 years. The next anniversary is 20 June 2027 — their 12th — which tradition marks with silk. The countdown updates daily, and the milestone list runs through crystal (15), china (20), pearl (30), sapphire (45) and emerald (55) along the way.

Common questions

Where do the traditional gifts come from?
A mostly Victorian-era list, standardised in the early 20th century and lightly different between countries — modern alternative lists exist alongside it. Treat it as tradition, not obligation.
What about anniversaries on 29 February?
Leap-day couples usually celebrate on 28 February or 1 March in common years — the calculator counts the year either way.
Does it work for non-wedding dates?
Yes — any start date works: a business founding, sobriety date, first day at a job. The gift line is just tradition for weddings.
