So that year is 1962. Probably, the Stan twins were 12 years old in that time, which is the current age of Dipper&Mabel because that same age will give story a strong detail. So, if they were 12 in 1962 that means they born on 1950. So, they are like 62 years old now.

That's a pretty good guess, maybe the best one.
