What date should I use for my anniversary?
Use whatever date feels meaningful to you! Common choices include: the day you started dating, your first date, the day you met, or when you became "official." The best date is the one you both agree on.
What is the 100 days anniversary?
The 100 days anniversary is a popular milestone in Korean dating culture (called "baegil"). Couples celebrate reaching 100 days together with gifts and special dates. It's become popular worldwide as a way to celebrate early relationship milestones.

Frequently Asked Questions

How do you count months in a relationship?

Count each calendar month from the day you started dating. If you started on the 15th, your monthly anniversary is the 15th of each following month.

What is the 100-day anniversary?

100 days is a popular milestone in many cultures, especially in Korea and Japan. It marks 100 full days since your relationship began.

Why is 520 days special?

In Chinese culture, 520 sounds like 'I love you' (wǔ èr líng ≈ wǒ ài nǐ), so 520 days is celebrated as a romantic milestone.

Is the anniversary calculator free?

Yes, completely free with instant results. No signup, no email required.

Does it work for marriage anniversaries too?

Yes. Just use your wedding date instead of your dating date and you'll get the same milestones counted from your marriage.
