Dating Age Range Calculator

Half your age plus seven is an old saying about age gaps, and this page does the arithmetic it describes. Enter one age to see the range the rule gives, from half the age plus seven at the bottom to twice the age minus fourteen at the top, or enter two ages to see whether they fall inside it. The result also shows the working, how wide the band is, and the largest gap the rule permits at the younger age. No research produced the saying and none supports it; two ages carry no information about whether a relationship is a good idea, and nothing here should be read as saying they do.
