What does monthsary mean?

Monthsary means a monthly anniversary. It is commonly used for relationships, dating milestones, friendships, and other events people celebrate every month after the start date.

How do I calculate my monthsary?

Count the number of full months between your start date and today. This calculator does that automatically and also shows your next monthly milestone date.

Is a 12-month monthsary the same as a 1-year anniversary?

Yes. The twelfth monthly milestone is also the first yearly anniversary. After that, you can keep tracking months or switch to yearly anniversaries.

Can I use this for work or friendship milestones?

Does the calculator store my relationship date?

No. The calculation runs locally in your browser and does not store or upload your date.
