Just type your birthdate and hit calculate to get your age in years, months, weeks, and days, for using this calculator as the how old am i calculator. To calculate your exact age, including months and days, you will have to subtract your birth months and days in numbers from the current months and days. Your age can be calculated by finding the difference between the date you were born and the current date. To calculate your age based on date of birth, you can simply count backwards in years from your birth year until todays year, in order to figure out how old you are on this current date.

To calculate your total age, figure out how many full years have passed since you were born. Once calculated, you are then going to add up the days, which would be the days between the date you were born last and your current date. We will then run the math for how old that person (or thing) is, based on whatever date you chose.

The formula to calculate chronological age is pretty straightforward, you simply need to subtract years from years, months from months, and even days from days. The simple arithmetic procedure involves evaluating one year of birth by the year of age that needs to be calculated. Also, the Age Calculator helps in finding the exact age, whether one wants to do calculations on a past date or a future date. The online age calculator also will give you an accurate age, months, years, dates, and weeks, if you would like to know your birth time, you just need to enter in a field, which will provide 100% accurate answers. Of course, it will give you just an approximate number for how old you would be at a given date -- it does not factor in your birth month and day as opposed to your present-day month and day. This means when someone is born, they are aged 0, and they will become 1 exactly one year after they are born, or, as we call it, their birthday.

For example, a person who has lived 3 years 11 months has an age of 3. The person who has lived 3 years and 11 months has an age of 3, and his/her next birthday is a month away. For example, if one child is born only a day before Chinese Traditional New Year, then after 2 days, that child will have reached age 2, although it is only 2 days old. Each month has either 30 days or 31 days, with the exception of February, which has 28 days in the regular year and 29 days in a leap year. The system used in this age calculator is the most widely used system of age. For these calculations, you input the date on which construction on the historic monument was completed, or the purchase of a vintage/collectible object, into the date-of-birth field, and the current date into either the current age or age-as-of field, in order to calculate the age of the monument or object. The age is displayed in years, months, and days.
