## Half-Your-Age-Plus-Seven Rule

The half-your-age-plus-seven rule is a mathematical guide to judge whether the age difference in an intimate relationship is socially acceptable. Mathematically speaking, the rule is (Minimum Age) = (Age of the Older Individual) / 2 + 7.

For example, if Shane is 30 and wants to date Kristen, who is 20, he would be in violation of the rule, since the minimum age being 22. Notice, however, that the age difference matters less as the potential partners grow older. In this case, Shane would have four years to wait before the age difference in the relationship was "socially acceptable".

Its half you age plus 5, not 7.

You're the only one I heard say it's plus 5/

There are other rules that are quite instilled in common knowledge such as the 20/25 rule and the +- 5 rule.

i thought the rule was mind your own god damn business and let people love who they want. but note that i said love, not make love to. haters.

Funny how those obsessed about age are the ones outside the relationship.

Actually, ya'll are being a little harsh. The rule is also applied by older men who are interested in younger women, but don't want to be perceived as "creepy."

Sometimes people adjust the "7", however this is rare and we have not noticed much movement towards "5".

At OneHalfPlusSeven.com we do not use the rule to refer specifically to intimate relationships as stated here. It refers more to romantic interest in general.

Technically speaking, as long as two people are not the exact same age, they will one day, or have already, fit this rule perfectly. One easy way to determine when two people will fit this rule is by downloading the iPhone app, "Dating Calc."
