How many days old are you if your 24?

Calculate the age of a person, place or thing. The age calculator calculates age given a date of birth in years, months and days. You can also use this calculator to find length of time between two dates.

The age calculator finds the age time span in years months and days, months and days, and in total days only.

How to Calculate Age

This age calculator uses 2 similar but slightly different methods to calculate age. One method is used to give age in years, months and days, and also months and days. The other method is used to very precisely calculate age in total days only.

When calculating age to the detailed level of days it's important to remember that not all months have the same number of days. Also, while a year has 365 days, a leap year has 366 days.

When you calculate age in terms that include years, this calculator provides the answer in common terms. For example, a teenager might say he is 15 years old rather than saying he's 12 normal years old plus 3 leap years old. This age calculator uses the same assumption -- although we know years may have different lengths, we generalize between regular years and leap years, and call them equal.

The same is true for months. If a baby is 7 months old, the parents would not say she is 4 months that are 31 days long, plus 2 months that are 30 days long, plus 1 month that is 28 days long. We typically generalize across months of different lengths, and count them all equal as general months.

The age calculator finds age in terms that are commonly used, calling all years equal and all months equal. When calculating days however, the calculator uses a function to find the precise number of days between dates.

If you wanted to know how many days you've been alive you need to account for extra days in leap years. You also need to know the total number of months with 31 days, total months with 30 days, and total months with 28 days.

The age calculator uses a function that recognizes how many leap years are in a given time span. It also calculates the specific number of days in a partial year. For example, if you were born on March 5 and today is June 7, the calculator finds the exact number of days that occur between those dates.

Your age in total number of days is calculated as:

• Number of years, x, with 365 days = 365x plus
• Number of years, y, with 366 days = 366y plus
• Number of days in the remaining partial year

This calculator assumes the start date is day 0 and begins counting one full day after day 0. For example if you input the dates 03/15/2022 and 3/18/2022 into the calculator you will get a total age of 3 days. Day 1 is the 16th, day 2 is the 17th, and day 3 is the 18th. The 15th is not counted in the tally of days.

Date Formats

The age calculator allows you to input single digit months and days. You do not have to pad them with a leading zero. You must input the 4-digit year however.

Have you ever wondered EXACTLY how old you are?  Down to the days, hours, minutes and even seconds! This age calculator will tell you exactly that! Calculate your age up until now, this exact second! Finally you will know the answer to “How Old Am I!?”

This Age Calculator Tool will give you a bunch of really important information 😉

Why exactly would you want to know your age with such precision?

Well for one, it makes for great dinner conversation.  And number two, people will respect you if you know this number.  I mean, just how many million minutes old are you?? Okay, I am kind of kidding (sorta), but seriously this would make for great trivia, since people probably don’t have a good ballpark idea of the answer.  AND the inner nerd in you is going to be super proud of you for knowing this information.   Think of all the famous fictional characters that would be excited by this.  I can hear Doc Brown (Back to the Future) yelling “PRECISELY!” at this very moment.

How to Use the “How Old Am I” tool

In the first box, simply enter in your birth year, month, and day.  If you want to get really granular, you can input your actual birth time as well (completely optional).  This part alone will give you your result in months, days, hours, minutes, and seconds.  All separately standing on their own. Check out here https://hughesairco.com/.  The tool will also return your zodiac sign in case you didn’t know it, or in case you are searching for how old somebody else is.  It will also tell you exactly how far away your next birthday is.

The second box (how old will i be on) will let you calculate your future age.  Simply input a future date, and it will output how old you will be on the given future date.  Please note that this tool (the second box) utilizes the birthday/age information that you have already inputted in the How Old Am I box (the first box), in order to give you your future age.   Some serious BTTF stuff right here!  Speaking of predicting the future, check out our How Tall Will I Be? tool to see how tall you or your child will be (assuming you are still growing).

Did you know?  Some Random facts about age and time!

The median age in the United States in 2015 was 37.8 years old.

The longest living person know to have lived on earth was Jeanne Calment of France, who was born in 1875 and lived to be 122 years & 164 days old!

The youngest current living person on earth is only 1 second old!  That is because an average of 4.3 babies are born every second (353 thousand babies are born every day as estimated by UNICEF).

The most well known number (okay, this one might be more opinion than fact!) related to granular time in a year is 525,600 minutes in a year, because of the popular song Seasons of Love (full video below) from the hit musical RENT.

For your enjoyment, watch Seasons of Love (525,600 minutes)!
