Why June 28 is the perfect Day of the Year

June 28 is the most mathematically perfect day of the year. Whether you write it 6/28 or 28/6, today is a perfect day.

A perfect number is a number that is the sum of its factors besides itself, and 6 (1+2+3) and 28 (1+2+4+7+14) are the first two perfect numbers. Hence, June 28 is a perfect day.

Perfect numbers are few and far between, so don’t hold out for a celebration in which the year is perfect as well. The last time that happened was in year 496, and the next time is over 6,000 years away, in 8128.

Mathematical date enthusiasts will note that today is also Tau Day, if you didn’t get enough circle constant celebration in March. Tau is the ratio of a circle’s circumference to its radius, and it is arguably a better constant than pi, the ratio of circumference to diameter. But if you choose to celebrate perfect numbers today instead of circle constants, you can transcend the transcendental number battle.
