There's an example follow the steps below.

• Add 18 to the month they were born

• Subtract 554
• Divide by 2
• Add their birth date

• Add 692
• Multiply by 20
• Add only the last two digits of their birth year
• Subtract 32940 to get their birthday!

That's some Pretty Cool Math Stuff!

Here's an example below...

Let's suppose someone has a birthdate of August 22, 1964.

So we want to use the format of month/day/year so this birthdate would be 08/22/64.

Notice we only used two digits for the year.

1) 18 + 8 = 26

2) 26 x 25 = 650

3) 650 - 333 = 317

4) 317 x 8 = 2536

5) 2536 - 554 = 1982

6) 1982 / 2 = 991

7) 991 + 22 = 1013 

8) 1013 x 5 = 5065

9) 5065 + 692 = 5757

10) 5757 x 20 = 115140

11) 115140 + 64 = 115204

12) 1295204 - 32940 = 82264

And there you have it....

8 . 22 . 64 which is the same as August 22nd, 1964!
