Typically, I hear the "Half Plus Seven" rule. Example: I'm 24. 24/2=12. 12+7=19. According to this rule I can date 19+.
Socially... People would probably still look at me a bit weird for dating someone 19 yo, but I don't think many people would call it "wrong".
That being said any age Gap over a few years is weird... but the larger the gap, the more weird... The older both parties are, the less weird.
For a 20 year gap with that rule, the youngest a couple could be would be about 33 and 52(gap is almost 20).
