📆 Anniversary Countdown

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.

A sample result

Say Jordan and Casey started dating on March 14 of last year and check the counter on a day in late September. The screen might read something like 560 "days together," 40 "days until your next 100-day milestone" (day 600), and 170 "days until your anniversary." That second number is the useful one: forty days is plenty of time to book a table or plan a picnic, and day 600 is a milestone most couples would otherwise sail right past.

How to read the numbers

• Days together is the running total, handy for a card ("1,000 days and I'd still pick you") or a caption.
• Days until your next 100-day milestone tells you when the next round number arrives, so it's the best one for small surprises.
• Days until your anniversary is your planning runway for the big yearly date.

Milestone ideas worth marking

• Day 100: the classic first checkpoint; a handwritten note or a favorite takeout night is enough.
• Day 365: recreate your first date as closely as you can remember it.
• Day 500: make a playlist with one song from every month you've been together.
• Day 1,000: a bigger outing, a weekend away, or a photo book of the first thousand days.
• Day 2,000 and beyond: write each other a letter to open at the next thousand.

Variations

• Two-date version: count from your first date and from the day you made it official, then celebrate both in a low-key way.
• Long-distance countdown: use the milestone number as the date for a planned visit or a shared video-call dinner.
• Wedding countdown: after the ceremony, restart from the wedding date and watch a brand-new tally begin.
• Friendship tally: works for best friends too; count from the day you met.

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.

Mistakes to avoid

Don't guess the start date; scroll back through your texts or photos to find the real one, because an off-by-a-week date throws off every milestone. Set the reminder a week before the milestone, not on the day. And don't let a counter turn into pressure: a milestone can be as simple as saying "hey, it's day 700" over breakfast.

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.

Gift timing made easy

The anniversary countdown doubles as a shopping deadline. Anything personalized, like an engraved piece of jewelry or a printed photo book, often needs two to three weeks to arrive, so when the number drops near thirty it is time to order. Restaurant reservations for popular weekend nights fill up early too, which makes the forty-day mark a smart moment to book.

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.

FAQ

How do I calculate how many days we have been together?

Enter your start date on this page and the counter shows the total days instantly, along with your next 100-day milestone and the days left until your anniversary. It does the math in your browser, including leap years, so you don't need a spreadsheet or a date calculator app.

What do couples do on their 100 days anniversary?

Most keep it small: a handwritten note, a favorite dinner, a short video of photos from the first hundred days, or recreating the first date. The point is acknowledging the milestone, not spending money. Many couples keep going with a little celebration every hundred days after that.

When is our 1000 day anniversary?

Type your start date into the counter and watch the milestone line. It lists the days until your next hundred-day mark, so once you pass day 900 it will be counting down to day 1,000. Add that date to your phone calendar with a reminder a week early.

Should we count our anniversary from the first date or when we became official?

Either works, as long as you agree. Some couples use the first date because it's the true beginning; others prefer the day they made it official because it feels more meaningful. Plenty keep both, marking the official day as the main anniversary and the first date more casually.

How many days is 2 years together?

Two years is 730 days, or 731 if a February 29 falls inside that stretch. The counter handles this automatically when you enter your start date, so the number you see on screen is exact rather than an estimate based on months.

Does the anniversary counter save my dates?

No. Everything is calculated in your browser, and nothing you enter is stored or sent anywhere. That also means you'll need to type your date again when you come back, so screenshot the result or copy the milestone dates into your calendar if you want to keep them.
