Relationship Days Calculator

Choose the day your relationship started. The calculator runs entirely in your browser and does not upload your date.

When did your relationship start?

Calculated locally in your browser. Your date is not sent to Flowment.

Keep the number in sight

Put your relationship days on your iPhone Home Screen.

Flowment can keep counting from your start date automatically, so the number is there whenever you unlock your phone.

“Together for” shows the number of complete calendar days since your start date. The start date itself is day 1, so “Today is day” is one higher.

Yes. Use the date that matters to both of you: when you met, when you became a couple, or another beginning you share.

Use a count-up card in Flowment to keep the same relationship-day count visible as an iPhone widget.
