What age range should a 40 year old man date?

Dating Age Rule. The dating age rule to determining a socially-acceptable age difference in partners goes something like this: half your age plus seven (40 = 20 +7 = 27) to define the minimum age of a partner and your age minus seven times two (40 = 33 * 2 = 60) to define the maximum age of a partner.

What is the maximum age gap in a relationship?

There are no maximum or minimum acceptable age gaps in relationships. (There is an exception: An adult having a relationship with a child under 18 violates boundaries.) Research shows that there is a correlation between lasting relationships and smaller age gaps of partners.
