How to Calculate Your Age
Getting started is as simple as entering your birth date. Whether you want to calculate your current age or see how old you were on a specific date, our tool handles all the math for you. Here’s a step-by-step guide to help you dive in:
- Enter your birth date: You can type it in (e.g., 10/02/1995 for “Feb 10, 1995”) or pick it from a calendar. See the small icon next to it.
- Set the target date: By default, the calculator will show your age as of today. However, you can choose any past or future date to see how old you were—or will be—at that time.
- Choose the time unit: Want to know your age in weeks, days, or even seconds? Select your preferred unit, and the calculator will provide an exact answer.
How Old Am I Today?
Let’s learn how to calculate your age manually, without using an age calculator. For this example, we’ll assume today is September 12, 2024, and you were born on March 20, 1998. Here’s how to work it out:
- Start with your birth date and go forward to your last birthday.
Your most recent birthday was on March 20, 2024, so subtract the years:- 2024 – 1998 = 26 years.
- Now that we’re on March 20, 2024, add as many full months as you can without going past today’s date.
- From March 20, 2024, adding 5 full months takes us to August 20, 2024.
- Lastly, count the remaining days from August 20, 2024, to September 12, 2024.
- That’s 23 days.
So, by adding everything together, you are 26 years, 5 months, and 23 days old on September 12, 2024.
How old will I be in 2050?
Calculating your age for a future date works just like it does for a past date. In the age calculator, simply adjust the default current date to a future one.
For example, if you were born on August 30, 1982, and you’re curious, “How old will I be in 2050?”:
- Enter your birth date (you can type in “30 08 1982”).
- Change the “Calculate age on” field to any date in 2050, such as January 1, 2050.
The calculator will instantly tell you that on New Year’s Day 2050, you’ll be 67 years, 4 months, and 2 days old.
