How Old Will I Be in a Future Year?

Subtract your birth year from the future year to get the age you'll turn during that year: born in 1995, you turn 55 in 2050. On a specific date, you're a year younger if your birthday hasn't come yet. Enter your date of birth and any date, past or future, for your exact age in years, months and days.

How to Use This Calculator

1. Enter your date of birth.
2. Enter a target date, or tap Age in 2030, 2040 or 2050.
3. Read your exact age on that day. It works for past dates too: how old were you on a given day?

Age in 2030, 2040 and 2050 by Birth Year

The age you turn during each year (on or after your birthday):

Before your birthday in that year, subtract one. For a deeper look at 2050, including days alive, read how old will I be in 2050.

Worked Examples

• Future: born 10 March 1995, on 1 January 2040 you'll be 44 years, 9 months and 22 days old. You don't turn 45 until 10 March 2040.
• Past: the same person on 4 July 2010 was 15 years, 3 months and 25 days old.

Why Not Just Subtract the Years?

Year subtraction tells you the age you reach during a year, not on a particular day. For deadlines, the day matters: an age cut-off on 1 September, a pension date or a visa rule. The calculator counts the full calendar dates, including leap years.

When People Use It

• Eligibility dates: school admission cut-offs, exams, sports age groups and job age limits.
• Retirement planning: your exact age on a planned retirement date.
• Milestones: how old you'll be at a child's graduation or a big anniversary.
• History: how old you were on the day of a famous event.

Counting down to your next birthday instead? Use the birthday countdown. For today's age, go to the age calculator; to compare two people, use the age gap calculator.

How the Age on a Date Calculator Works

The calculator counts from your date of birth to the target date in complete years, then complete months, then remaining days, borrowing days from the previous month when needed, exactly as an age is counted today. Because it uses real calendar dates, leap years and month lengths are handled automatically, which is why it can differ by one year from simply subtracting the years.

How the Age on a Date Calculator Saves You Time

Subtracting years gives the wrong answer for anyone whose birthday falls later in the target year. The calculator gives the exact age on any date, past or future, in one step.
