Age Calculator (How Old Am I?)

How old am I today?

Your age today can be calculated using your date of birth. By using mathematical calculation, we can work out how many years, months, weeks and days have passed since you were born. If you know the time of your birth, it can be incorporated into the calculation to provide an even more precise result.

How old was I on X date?

Should you want to know how old you were on a certain date in past history, or how old you will be at a future date, we've got you covered. Simply use the 'Age at Date' option in our calculator and enter a date in either the past or future. Our calculation tool will then calculate based upon that date.

Calculating your age

Your age can be calculated by finding the difference between your date of birth and the current date. What we are specifically finding out is how much time has passed since you were born. We can, of course, perform a rough calculation by subtracting the year of your birth from the current year, which will give you a figure for how many years old you are, or will be, in the current year.

As an example, if I was born in 1995, my age in 2025 will be: 2025 - 1995 = 30 years.

Of course, this only gives you a rough figure for how many years old you will be in the current year - it doesn't take into consideration the month and day of your birth compared to today's month and day. To calculate your exact age, including months and days, you need to deduct the numerical month and day of your birth from the current month and day.

How many days old am I?

People often ask how they can work out their age, and I point them to this calculator (it's one of the reasons I created it). Although you can have a rough guess by multiplying your age in years by 365, you could still be out by up to several hundred days. This will in most part be because you'll be working on the basis of your age at your last birthday, and therefore excluding the days since.

There's also leap years to take into consideration. These occur once every four years and mean an extra day in the calendar (366 days in the year). Your best way to get an accurate calculation to how old you are in days is, therefore, to use the age calculator tool provided.

How old will I be in 2050?

Working out your age in the future is a simple process with our age calculator. Here's how to calculate how old you will be in 2050:

1. Enter your day, month and year of birth.
2. Set the 'age at date' to January 1 2050.
3. Click the 'Calculate' button to find out what your age will be in 2050.

How old was the oldest person ever?

The oldest person ever recorded was Jeanne Calment, a woman from France. She was born on February 21, 1875 and lived until the age of 122 years and 164 days before passing away on August 4, 1997. 1

Of the top 10 oldest people ever, all 10 are currently women. The oldest man ever is currently recorded as being Jiroemon Kimura from Japan. Plugging his date of birth into our age calculator tool reveals that he lived until the age of 116 years and 54 days. He passed away on June 12, 2013.

With that said, Fredie Blom, a South African man born on 8 May 1904, was recorded as 'unofficially' the world's oldest man ('unofficial' because he wasn't listed in the Guinness Book of World Records). Fredie died on 22 August 2020 at a said age of 116 years, 3 months, and 14 days.

How to age well

A government researcher once quipped that "Age is an issue of mind over matter. If you don't mind, it doesn't matter." Luis Bunuel, the Spanish filmmaker, joked that "Age is something that doesn't matter unless you're a cheese". Perhaps we can also add wine to that list?

These quotes are, of course, meant to be whimsical. There's little doubt that while you can't control your age, or predict what might happen to you, you can take actions to keep yourself healthy and give yourself the best chance of reaching a ripe old age. From food, to exercise and looking after your mental health. Here's a great article about how to age well from the New York Times.
