Let’s take for example the age gap between someone born on April 17 1990 and someone born on August 29 1994.
The result is: ■ The age difference between the two persons is 4 years, 4 months, 12 days.
Nonetheless, in 2017 the concept of dating someone significantly older, or younger, than you still raises a few eyebrows.
After analysing 3,000 people, it found that couples with a five-year age gap are 18 per cent more likely to split up than those of the same age.
Interestingly, that figure rose to 39 per cent for couples with a 10-year age gap and a shocking 95 per cent for those with a 20-year age gao. Contrary to popular belief, researchers believe that the sweet spot lies in just a one-year gap between spouses who have a much smaller chance of separation at just 3 per cent.
With an age gap of 25 years, Macron, recently spoke out about the international obsession with the age difference between himself and his partner.
“If I was 20 years older than my wife, nobody would think for a single second that we couldn’t be legitimately together,“ he told Le Parisien.
■ Person 2 is older than Person 1 with 4 years, 4 months, 12 days.
■ Person 1 is 24 years, 9 months, 7 days old, while Person 2 is 20 years, 4 months, 26 days old.
In its earliest appearances, this rule is often cited as having French origins, although this citation always seems to appear in English-language (British or American) sources, leaving its true origin mysterious.
Another, somewhat vaguer metric often cited is declaring an age gap creepy when a partner is "old enough to be your mother/father," carrying with it as it does implications of symbolic Parental Incest or Wife Husbandry.
This trope is when a specific formula or calculation is proposed to determine either the "ideal" age gap, or the maximum allowable age gap before it becomes "creepy".
