What is an anniversary calculator?
An anniversary calculator is a free tool that tells you the exact number of days, hours, and minutes since a specific date — the day you started dating, got engaged, or married. Unlike a basic date calculator, our tool also identifies your next relationship milestone and suggests meaningful ways to celebrate, including creating a personalized digital gift page. Whether you are counting days since your first date or preparing for your golden wedding anniversary, this calculator makes it simple.
Why tracking your days together matters
Every relationship is built from thousands of small, unremarkable moments that quietly become the most important ones. Knowing you have been together for 500 days or crossed the 1,000-day mark turns an ordinary weekday into a reason to pause and appreciate how far you have come. Research shows that couples who actively celebrate milestones report higher relationship satisfaction. Many partners use day-count milestones as a prompt to do something thoughtful — write a heartfelt letter, revisit the place where they first met, or create a personalized gift page filled with their photos, songs, and memories.
Types of anniversaries you can track
This calculator works for any type of anniversary. Wedding anniversaries are the most traditional, but modern couples also track dating anniversaries, engagement dates, and even friendship milestones. In South Korea, the 100-day anniversary (known as baegil) is celebrated as a major relationship milestone. In many Latin American cultures, couples celebrate their monthly dating anniversary (mesiversario) during the first year. Work anniversaries matter, too — recognizing years of service builds loyalty and morale. Whatever your milestone, this tool helps you track it.

Common relationship milestones and what they mean
Every number tells a story. Here are the milestones that couples around the world celebrate:
- 100 days — The first big marker. In Korean culture, baegil is celebrated with a special date and gifts. It signals that the relationship has moved past the early uncertainty.
- 200 days — A quieter milestone, but many couples use it to reflect on growth. A handwritten letter or a surprise dinner goes a long way.
- 365 days (1 year) — The first anniversary. Traditional gift: paper (a love letter, a book, concert tickets). A perfect occasion for a MiMomento gift page with your first year of photos.
- 500 days — A popular social media milestone. Couples share their day count on Instagram and TikTok with photos and songs from their journey.
- 730 days (2 years) — Traditional gift: cotton. Many couples create a shared memory album or a personalized gift page to mark two years of memories.
- 1,000 days — The four-digit club. This is one of the most celebrated modern milestones, especially among younger couples. A gift page with a timeline of your 1,000 days makes an unforgettable surprise.
- 1,825 days (5 years) — Traditional gift: wood. This milestone represents strength and solidity. A carved keepsake, a tree planted together, or a MiMomento page with five years of highlights.
- 3,650 days (10 years) — Traditional gift: tin or aluminum. A decade together is a major achievement worth a grand celebration.
