Hint 5

Hint 6
​Each date is the date that a certain country joined the U.N. Each of these countries has exactly 6 letters in their name, and the highlighted number will tell you the location of letter you need (spatially, the number is not an index). So if the first date is 20/09/60 and the country is Cyprus, then the letters you want for that one are "pr."
