How the time together is counted
The calculator counts whole years since the date, then whole months, then the days left over, which is how a calendar does it. The total in days is the number of midnights between the two dates. Leap days are included, so a couple who got together on 3 March 2019 reach their 2,800th day on 1 November 2026.
Day milestones worth noticing
Anniversaries come once a year. Round numbers of days come at odd moments and nobody has made a card for them. The 100th day, the 500th, the 1,000th and the 5,000th all arrive on a date you can work out and plan a small thing around. The calculator shows the next few.
Traditional gift themes
One common list of traditional wedding-anniversary themes is below. Lists vary by country and over time, and many couples ignore them, but they are a handy way to break a blank.
| Year | Theme | Year | Theme |
|---|---|---|---|
| 1 | Paper | 10 | Tin or aluminium |
| 2 | Cotton | 15 | Crystal |
| 3 | Leather | 20 | China |
| 4 | Flowers or fruit | 25 | Silver |
| 5 | Wood | 30 | Pearl |
| 6 | Iron or sugar | 40 | Ruby |
| 7 | Wool or copper | 50 | Gold |
| 8 | Bronze | 60 | Diamond |
What to put in the card
The prompts on this page are short on purpose. A few true lines about one thing they did this year usually land better than a long paragraph about love in general. Write one specific memory, say what you noticed, and sign it.
