Rule dating age difference
Graph of the Half-age-plus-seven rule ("never date anyone under half your age plus 7"), which claims to dictate what age disparity between two people is acceptable in dating/romantic/intimate relationships during the late 20th century / early 21st century (called the "Standard creepiness rule" in the xkcd webcomic).According to this rule, the age of the younger person should not be less than half the age of the older person plus seven years, so that (for example) no one older than 65 should be in a relationship with anyone younger than 39 and a half, no one older than 22 should be in a relationship with anyone younger than 18, and no one under 14 years of age should be in a relationship at all...In its first known appearances (in the book Her Royal Highness Woman by Max O'Rell, "The little shepherd of Kingdom Come" by John Fox, and the 1951 play The Moon is Blue by F.Hugh Herbert), it's stated or implied that at the beginning of a relationship or marriage, the woman's age "is supposed to be half the man's age, plus seven", which gives a different (asymmetrical) interpretation to the rule.Similarly, in his autobiography, George Arnold Escher (1843-1939, father of famous artist M. Escher) claimed that when he was looking for a wife ca.1880, he thought that the ideal ages for husband and wife at marriage would be if the woman's age was half the husband's age plus 10.

To read the chart, go to the position along the x-axis which corresponds to your age, and the green range (between the black and red lines) directly above that position corresponds to the range of your partner's ages which is deemed acceptable by the rule.This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it.
