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 youngest I can date?

This rule states that by dividing your own age by two and then adding seven you can find the socially acceptable minimum age of anyone you want to date. So if youre a 24-year-old, you can feel free to be with anyone who is at least 19 (12 + 7) but not someone who is 18.
