Assuming a lifespan of 80 years, in what years of the 20th and 21st centuries (1900-1999), (2000-2099) would you have to be born to have the maximum number of prime birthdays in a prime year?

In what years of the same time spans would you have to be born to have the minimum number of prime birthdays in a prime year?

You may assume that people born on Feb. 29 in a leap year still celebrate their birthdays each following year.
