Add 18 to the month they were born
Multiply by 25
Subtract 333
Multiply by 8
Subtract 554
Divide by 2
Add their birth date
Multiply by 5
Add 692
Multiply by 20
Add only the last two digits of their birth year
Subtract 32940 to get their birthday!

I need to understand why this works. A break.Can someone help?
