June 28 - A "Perfect" Day

[debodun]

On the only date in the year for which the day number and the month number are both perfect numbers.
A perfect number is a positive integer that equals the sum of its proper divisors (divisors excluding the number itself).

Please explain further using the math. I'm a "numbers guy" and I just don't see what you mean?

28 is 7 times 2 times 2, 7 plus 2 plus 2 is 11?

For me, at 2:39PM June 28th was my son’s birthing day. He would be 52 today, had I not lost him in a car accident when he was 19 — I remember “that phone call” vividly.

Yes, he was perfect. A much better and more tolerant human than his mom or his dad——-

June is the 6th month. it's divisors are 2, 3 and 1 (2x3x1=6). Add those together and it's 2+3+1=6.
The 28th day: Divisors of 28 are 14, 7, 4, 2 and 1. Add those and it equals 28.

If you include 1 as a divisor of 6, shouldn't you also include 6?

If you include 1 as a divisor of 28, shouldn't you also include 28?

Not according to the info I was given.

Well this certainly is an odd formulation. Normally such mathematical little gems rely on prime numbers only. But OK it makes for a cute little thread!
