## How do I calculate age in years, months, and days?

To calculate someone's age in years, months, and days:

- Find the differences between the person's birth
**year/month/day**and the current**year/month/day**:`years = birth_year - current_year`

;`months = birth_month - current_month`

; and`day = birth_day - current_day`

.

- Replace them in the following formula:
`age = (years × 365) + (months × 31) + days`

. **Divide the result**by`years`

from step**1**and**truncate**it to get the age in**years**.**Multiply the remainder of step 3 by 12**and truncate it to get the**months**.**Multiply this last remainder**by**31**to get the**days**.

🙋 This result is an approximation since not every month or year has 31 or 365 days, respectively. Use our age in years, months, and days calculator to get the exact result!

## How old will someone be/how old someone was on a specific date

With our age in years, months, and days calculator, you can also **find a person's age on dates other than the present time** 👶👩🧓.

For example, if we wanted to find **how old a celebrity was at the time of their passing**, we can input the person's **birth date** into the calculator and their decease date in the "**Current date**" field.

Our calculator will then output the exact amount of **years, months, and days that the person lived throughout their entire life**!

Similarly, we can input a **future date** ⌚ to find how old will you or someone else's be at that time.
