Anniversary calculator

The exact time since a wedding, a relationship or joining a company, how long until the next anniversary and its traditional name.

How it works

Time is counted in full years, then months and days since the last anniversary, just like an age. If the date is 29 February, in non-leap years the anniversary falls on 1 March.

Each wedding anniversary has a traditional name: paper for the first, silver at 25, gold at 50 and diamond at 60. You’ll also see the next round milestone in days (1,000, 2,000…), another way to celebrate.
