Today's Flag Day, officially established by President Woodrow Wilson in 1916. It's also my sister Beth's birthday, and Gloria's friend Beth's birthday--same year, too, but that's classified information, still.
I won't give out their last names, but if you know them, and knew their REAL first names (one's is Mary Elizabeth, the other's is Bethany), you could go to BirthDatabase.com and, armed with first name, last name, and a rough estimate of their actual age, nail the birth year.
Happy birthday, girls. Many more. In fact, basic gender-based actuarial tables say 25.22 more. The single-life expectancy tables (for beneficiaries) say 27.0 more. Either way, it's a while before final checkout. Enjoy. Understand, too, that these are broad averages culled from the population at large and do not take into account healthier lifestyles.
