   • In the ‘Date of Birth’ field, enter your birth date using the format MM/DD/YYYY.
2. Choose the Date to Find Age On:
   • In the ‘Find Age on’ field, enter the date on which you want to calculate your age, also in the format MM/DD/YYYY.
3. Review Your Age:
   • Once both dates are entered, the calculator will automatically compute and display your age in the ‘Your Age’ field, typically in years.
4. Understand the Detailed Breakdown:
   • The ‘Years + Months + Days’ fields will break down your age into the exact number of years, months, and days.
   • The ‘Total Months + Days’ field will show the total age in months and days, without counting the years.
   • ‘Total Days’ displays the total number of days you’ve been alive.
   • The ‘Hours’ field calculates the approximate number of hours you’ve lived.
   • The ‘Minutes’ field shows an estimate of the total minutes you’ve been alive.
   • Finally, the ‘Seconds’ field will display an estimate of the total seconds of your age.
5. Use for Different Dates:
   • You can use the calculator to find out your age on different past or future dates by changing the ‘Find Age on’ date and the calculator will update all fields accordingly.

Frequently Asked Questions

How do you calculate how old you are?

Calculating your age involves determining the difference between your date of birth and the current date. Here’s how you can do it manually:

1. Identify the Current Date: Note the current day, month, and year.
2. Identify Your Birth Date: Know your birth day, month, and year.
3. Calculate the Years: Subtract the year you were born from the current year. This gives you an initial figure for your age.
4. Adjust for the Current Month and Day:
   • If the current month is less than the month you were born, you have not yet reached your birthday for the current year, so subtract one year from your age.
   • If the current month is the same as the month you were born, but the day is not yet reached, also subtract one year.
   • If the current month is the same and the day is the same or has passed, your age is correct as initially calculated.
5. Account for Months and Days: If you want to know your exact age in years, months, and days:
   • If the current day is before your birth day, you need to subtract one month from your age and calculate the days accordingly, considering the number of days in the previous month.
   • If the current day is the same or after your birth day, count the days from your birthday to the current day to find out the number of days along with the months and years.

How do you manually calculate age?

Calculating your age manually is a matter of comparing the current date to your date of birth. Here’s how you can do it step by step:

1. Write down the Current Date: Make a note of the current year, month, and day.
2. Write down Your Date of Birth: Record your birth year, month, and day.
3. Subtract the Birth Year from the Current Year: This gives you an initial figure for your age.
4. Consider the Months:
   • If the current month is before your birth month, subtract one from the initial age figure because you haven’t reached your birthday yet this year.
   • If the current month is after your birth month, the initial age figure is your age.
   • If the current month is the same as your birth month, proceed to the next step.
5. Consider the Days:
   • If today’s date is before your birth date, and the current month is the same as your birth month, subtract one from your age.
   • If today’s date is the same or after your birth date, and the current month is the same as your birth month, the initial age figure is your age.
6. Adjust for Leap Years (optional): If you want to be precise and the period includes February 29th on a leap year, you might need to account for this extra day.
   • Here’s a manual example:
     • Current Date: December 12, 2024
     • Birth Date: November 20, 1990
   • Calculate the year difference: 2024 – 1990 = 34

Since the current month (December) is after the birth month (November), we do not need to adjust the year.

So, the age is 34 years old.

If you want to be precise to the exact number of months and days, you could use a calendar to count them, or you could perform the following:

• If today’s date is past the birth date in the month, the number of months is the difference between the birth month and current month.
• If today’s date is before the birth date in the month, subtract one from the number of months and calculate the number of days separately based on the days in the previous month.

For example, if today were November 10, 2024, then:

• The year difference would still be 34.
• Since the current date is before the birthday in November, you would still be 33.
• You would count the months from November last year to November this year (but not including this year’s November), and then count the days from the birth date to today’s date.
