Practical guide
Using the How Many Days Have We Been Together? well
Who this is for
Couples who want a day count from the start date they both still tell—not a social-app anniversary.
Worked example
Started 18 October 2019 → thousands of days by 2026; the 1,000th day is a separate countdown if you have not hit it yet.
Say which clock you used
Known-since and together-since can differ by years. The percentage-of-life page needs a birthday as well. None of these scores a relationship.
Common pitfalls
- Mixing the day you met with the day it became a relationship
- Treating the count as a reason to stay or leave

Frequently Asked Questions

The day you met—not the day you made it official. Type that date and get years, months, and days. Arguments about “when it counted” are not the calculator’s job.
What Percentage of My Life Have We Been Together?
Relationship Curiosity
Days together divided by days you have been alive. High school sweethearts get a bigger percent than people who met at 34. Neither is a score.

1,000 days is about 2 years and 9 months. If you already passed it, the page says how long ago instead of inventing a future party.
