Simply enter the date (and optionally the time) your relationship started. The calculator measures the difference between that date and right now, then breaks the total duration into years, months, weeks, days, hours, and minutes so you can see exactly how long you've been together.
That's entirely up to you! Most couples use the date they officially became a couple, but others choose the day they first met, their first date, or even the moment they said 'I love you' for the first time. Use whichever date feels most meaningful to you.
Common milestones include 100 days, 6 months, 1 year, and every anniversary thereafter. Many couples also celebrate 500 days, 1,000 days, and significant multi-year anniversaries like 5 or 10 years together. The calculator highlights your upcoming milestones so you never miss one.
Absolutely. The calculator works for any couple regardless of location. Tracking shared time can be especially meaningful for long-distance couples, serving as a reminder of commitment and the journey you're both on together.
Make sure the start date you entered is in the past. If you accidentally enter a future date, the calculator won't be able to compute a duration. Also double-check that the date format is correct — use the date picker to avoid entry errors.
Milestone celebrations don't have to be grand — a heartfelt letter, a favourite shared meal, or revisiting the place you first met can be just as meaningful as a big trip. The key is acknowledging the moment together and reflecting on how far you've come.
Yes. If you add a start time, the calculator measures your duration down to the minute from that exact moment. If you leave it at midnight (00:00), the duration is calculated from the start of your chosen date.
Tracking your relationship timeline encourages reflection on shared experiences and growth. Research from institutions like The Gottman Institute shows that couples who regularly acknowledge and celebrate their relationship tend to have stronger emotional connections and better communication.
