Demonstration, because math is fun: x/2 7 = y x/2 = y - 7 x = 2(y - 7) x = 2y - 14I've read about the "half plus seven rule", not as advice, but as the male ideal.
Ideally, a guy wants to date a woman half his age 7.
I've done some googling ( This rule has been variously attributed to the French, and Muslims, and Jewish matchmakers; but who cares about it's origins, it works.

This is a quick calculator that allows you to compute the age difference in a relationship or between any two people.
It simply generates the ages of the two subjects according to the birth dates you input in the form and once you press Calculate it delivers the result.
This implies that the age of the older person should be at most twice the younger person's age minus 14 years, and there's no inconsistency based on which version of the rule you pick. I've also heard of "2x - 7" for the upper age limit. The problem with this is that you get different ranges of age depending on which person you're considering.
