Why Couples Count the Days
The big anniversaries are easy to remember — it's the in-between milestones that make a relationship feel celebrated all year. Hitting 500 or 1,000 days together is a genuinely sweet reason to plan something, and knowing the exact number turns an ordinary Tuesday into a reason to show up.
Use your milestone as a prompt. When one's coming up, browse our anniversary surprise ideas or grab a message from our anniversary wishes. Planning a wedding milestone? Pair this with our wedding hashtag generator.
Anniversary Calculator FAQs
How does the anniversary calculator work?
Enter the date you became a couple (or your wedding date). The calculator instantly shows how long you've been together broken down into years, months, and days, plus your total days, weeks, and hours together, the weekday you started, and your next big milestone.
What counts as a relationship milestone?
Popular milestones include your first 100 days, 500 days, 1,000 days, and each yearly anniversary. Many couples celebrate the day-count milestones between anniversaries — this tool shows the next few coming up so you never miss one.
Can I use it for a wedding anniversary?
Absolutely. Enter your wedding date instead of your dating start date and you'll see your married years, months, and days, plus upcoming wedding anniversaries.
Is the anniversary calculator free?
Yes, completely free with no sign-up. Your date stays in your browser — nothing is saved or shared unless you copy your result.
