About this anniversary calculator

An anniversary calculator answers two questions couples, friends, and colleagues often ask: how long has it been, and when is the next one? It counts whole years, months, and days from the start date, which is how anniversaries are usually described, and gives the same span in weeks, months, hours, and minutes. The next anniversary comes with its weekday and a live countdown, and for weddings the traditional and modern gift themes used in the United States. Milestones go beyond yearly anniversaries: the 100th, 1,000th, and 10,000th days, one million minutes, one billion seconds, and named anniversaries such as silver and golden.

How to calculate an anniversary

  1. Choose the occasion. Pick wedding, relationship, friendship, work, or another occasion, and add names if you like.
  2. Enter the start date. Choose the day it began. Leave As of empty to count up to today, or pick another date.
  3. Press Calculate anniversary. See how long it has been, count down to the next anniversary, and look ahead to the next milestone.

Frequently asked questions

What are the traditional anniversary gifts?

They are themes for each wedding anniversary, such as paper for the 1st, wood for the 5th, silver for the 25th, and gold for the 50th. Modern lists offer updated alternatives, such as clocks for the 1st.

When is the 1,000th day together?

It falls 1,000 days after the start date, about 2 years and 9 months later. Many couples celebrate it as a fun extra milestone; it appears in the milestone list.

What if we married on 29 February?

In years without a 29 February, the anniversary is placed on 28 February, the last day of the month, so you always have a date to celebrate.

What is a silver or golden anniversary?

A silver anniversary marks 25 years and a golden anniversary 50 years. Others include pearl (30), ruby (40), and diamond (60).

Can I use it for a work anniversary?
