SOME THINGS ARE WORTH KEEPING

Written in your numbers.

Make a keepsake for your next anniversary, or just because. Your dates, your little rituals, your wonderfully one-of-a-kind story.

Create your story

A few little things to know.

Are these things we’ve actually done?

Calendar facts come from your dates. Everyday moments and activities use editable habit estimates. Scientific conversions offer a little cosmic perspective. You can change the assumptions or hide any fact.

Can I make this for an upcoming anniversary?

Absolutely. Set “Calculate up to” to the anniversary you’re celebrating. All results and exports use that date.

Where does our information go?

Your names, dates, habits and photos stay in this browser session. No account is needed. Downloading a keepsake doesn’t publish anything.

How do you handle leap years?

We use calendar-aware date arithmetic. February 29 anniversaries fall on February 28 in non-leap years. Your wedding day starts at day zero.

How long have we been married?

Enter your wedding date to calculate your marriage duration in calendar years, months and days. Choose today or a future anniversary as your report date, explore your numbers, then save a personalised anniversary picture to share with each other and the world.

Find your next British wedding anniversary

The next little celebrations include traditional British anniversary materials: paper for one year, wood for five, tin for ten, silver for 25, pearl for 30, gold for 50 and diamond for 60. Open the full anniversary calendar in your results to see later celebrations, including stone at 90 years. Traditions vary between countries and sources.

Questions about your anniversary calculator

Does it account for leap years and different month lengths?

Yes. Your calendar duration follows the actual dates, including leap years and months of different lengths. The start date is excluded and the report date is included in the day count. Time-based totals use the selected time zone.

Are the everyday facts exact?

Calendar facts come from your dates. Coffee, films, hugs and other habits are playful estimates using clearly stated frequencies. Choose Personalise to adjust them to your life. Scientific comparisons use the average rates explained in How we calculate.

Can I make an anniversary picture for Instagram or other social media?

Yes. Choose four favourite facts and create a square (1080 × 1080), portrait (1080 × 1350) or story (1080 × 1920) PNG. Add your own photo or message, hide names or dates if you prefer, and download or use your device’s share menu.

Is it free, and do I need an account?

The calculator and picture downloads are free. No calculator account is needed. Your names, dates and photos are processed in your browser and are cleared when you refresh.
