Calculate easily and accurately if the age gap between you and your desired partner is socially acceptable

Welcome to the website and calculator dedicated to the relationship age gap rule with day precision! First and unique in the entire world, giving you the most accurate calculation if the age gap between you and your desired partner is socially acceptable.

There is a widespread relationship age gap rule - referred to as the half your plus seven rule in Wikipedia.

And there is now the relationship age gap rule with day precision, overcoming the limitations and improving the accuracy of the widespread relationship age gap rule.

The widespread relationship age gap rule states that:

• In order to find the socially acceptable age of your youngest suitable dating partner, you should divide your current age in years by 2 and then add 7.

Here are the two steps how to calculate this for someone who is 25 years old:

1) 25 / 2 = 12.5
2) 12.5 + 7 = 19.5

19.5 should supposedly mean 19 and a half years old.


• In order to find the socially acceptable age of your oldest suitable dating partner, you should subtract 7 from your current age in years and then multiply by 2.

Here are the two steps how to calculate this for someone who is 25 years old:

1) 25 - 7 = 18
2) 18 * 2 = 36

However, the widespread relationship age gap rule works with very low precision - half a year - causing as a result a few issues (elaborated here).

The dating age calculator on this website rests on a much higher precision - one day - fixing in this way all of these issues.

Enjoy it!

The dating age calculator yields two result views: "years and days" and "years, months, days".

The results are generated for the "years and days" result view. The "years, months, days" result view is a reformatted, more user-friendly (especially when a result has a lot of days) "years and days" result view.

All results are always accurate. Sometimes however a result may have a weird detail or be ambiguous due to the following scientific facts:

1) A year may be 365 or 366 days long. For example, a year back from 2019-Mar-01, till 2018-Mar-01, is 365 days long. However, a year back from 2020-Mar-01, till 2019-Mar-01, is 366 days long because of 2020-Feb-29. (Years that are 366 days long are known as leap years.) This may affect both result views.

2) A month may be 28, 29, 30 or 31 days long. For example, a month back from 2020-Mar-01, till 2020-Feb-01, is 29 days long. A month back from 2020-Feb-01, till 2020-Jan-01, is 31 days long. This may affect the "years, months, days" result view.

If a result has a weird detail, an explanation is available. If a result is ambiguous, the title of the result is marked with an asterisk and an explanation is available.

Since the precision of the dating age calculator is very high - one day, it will give you a different result regarding the age values of your oldest and youngest suitable partners every day.

As a person gets older, more and more people become suitable for her or him - in both directions:

Once two people become compatible per the relationship age gap rule with day precision, they remain compatible per it forever.
