📆 Anniversary Countdown

Pick your start date to see how many days you've been together, when your next 100-day milestone lands, and how long until your anniversary.

What the counter shows

Choosing a date gives you three numbers. First, the total days you've been together. Second, your next 100-day milestone: 100, 200, 300 and so on, the round numbers plenty of couples use as an excuse for a small celebration. Third, the days left until your anniversary, which is really just a way of asking how much time you have to plan something and buy a gift.

Why counting days helps

Months slip past and anniversaries have a habit of being remembered with about a week to spare. Counting in days makes the time feel real and nudges you into planning early. It also spreads the celebrating out, so instead of one date a year you get little checkpoints scattered through it.

How to use it

Enter both names and your start date and the numbers appear instantly. Screenshot them, or drop the upcoming date straight into your phone's calendar as a reminder. You can count from your first date, from the day you made it official, or from your wedding day. Just decide together which one you're using so you don't end up with two anniversaries.

The counter also shows the thresholds ahead of you, like day 500 or day 1,000. Seeing them in advance makes it much easier to have a small surprise ready on time, even if you're not planning anything big.

The anniversary counter is free, needs no sign-up, and does all its math in your browser. Come back and check it as often as you like throughout the year.
