They still don't get the age thing.
I am suggesting that those who would know, be careful and sure about their calculations.
Let us do some numbers.
A man know to have been born on the 1st of January 1980, would have turned 10 on the 1st January 1990.
Everything that happened to him while he was ten happened during the course of that year.
At the other extreme, if he had been born on
the 1st July 1980, then all the events in the first half of 1990, as well as all the events in the second half of 1989, occurred while he was nine. After the milestone birthday anything happening in the second half of 1990, and the first half of 1991, occurred while he was ten.
So the assertion that "A man known to be born in 1980 says he was 10 when something occurred. People will assume and record that it occurred in 1990." will only be always true if it is understood that the people making the assumption and the people paying attention to the assumption, are aware that the man was born on the 1st of January.
In general when matching a year with an age, it is better to
assume a discrepancy of + or -1.
So: He says he was 10 at the time -- it was perhaps 1990 or 1991.
Or: He says it occurred in 1990 - he was either 9 or 10.
