MAY I GUESS YOUR BIRTHDAY ?
write down the month in which you were born (eg. march=3)
Multiply the month by 4
Multiply by 25
Add the day of the month you were born (eg 8 march=8)
Multiply by 2
Multiply by 50
Add the last two digits of your year of birth (1986)
Subtract 10500 from the result
you get the result, first digits are the month of birth , after that date of birth and then year of birth
plz use a calculator for this calculation .
