Before going through steps to find your age, we will need to know some very important rules. So,

- Rule [1]: Always write your age in the format DD(day) MM(month) YYYY(year).
- Rule [2]: Subtract from Left to Right, different from normal subtraction which we do Right to Left.
- Rule [3]: If you take one carry from MM(month) to DD(day) always
`add 30 to the DD(day) value`

, because 01 Month = 30 Days. - Rule [4]: If you take one carry from YY(year) to MM(Month) always
`add 12 to the MM(Month) value`

, because 01 Year = 12 Months.
