Formula for dating age difference

Example: A 80 year old women may date a man of anywhere from 47 years to 146 years old. From what Ive read in historical fiction it seems as if it was once more socially acceptable to date/marry younger women then you can in 21st Century America. Meaning that it's the youngest a MAN can go without people wondering about him (I know there are lots of exceptions!!

I call the "1/2 your age 7" rule the "socially correct rule", or something like that.

So a 10-year old man can only date women 12 or older? A 80-year old man and a 47 -year old woman would definitely raise some questions too.

I say it only applies to men because it is generally more socially common for men to date somewhat younger women (as in the above examples) but not the other way around. Though there are all kinds of exceptions and contrary examples, I know I know. Odd that I'd never heard of this rule before, but maybe there's something too it.

For example, if one baby was born just one day before the Traditional Chinese New Year, 2 days later the baby will be at age 2 even though he/she is only 2 days old. However, there are two ways to calculate the age from Feb.

In some situations, the months and days result of this age calculator may be confusing, especially when the starting date is the end of a month.

The confusion comes from the uneven number of days in different months.

Fortunately, the very question of what is considered too young-or old-has been pondered by the French, who developed a useful formula called "Half Your Age Plus Seven?

" To determine the range of what is considered socially acceptable, divide your own age in half and then add seven.
