How to calculate someone's age

Example #1:

Suppose someone was born on March 15, 1985. How old is the person on October 8, 2024?

1. Start by finding the number of years the person has been alive.

Number of years is 2024 - 1985 = 39 years

2. Check if the birthday has occurred this year:

Birth Month: March

Current Month: October

Since October is after March, the birthday has occurred this year and the person has already turned 39.

3. Since birthday has occurred already, find the number of months and/or days after birthday

Months from March 15 to October 15: 7 months (April, May, June, July, August, September, October)

However, since the day is October 8, 2024, the seventh month is not completed just yet.

Therefore, so far the person is 39 years and 6 months old

4. Calculate the number of days

23 days (from September 15 to October 8)

Example #2:

Suppose someone was born on December 4, 1985. How old is the person on October 8, 2024?

1. Start by finding the number of years the person has been alive.

Number of years is 2024 - 1985 = 39 years

2. Check if the birthday has occurred this year:

Birth Month: December

Current Month: October

Since October is before December, the birthday has not occurred this year. The person is still 38 years old. 

3. Find the number of months and/or days after birthday

Months from December 4 to October 4: 10 months (January, February, March, April, May, June, July, August, September, October)

Since the day is October 8, 2024, the seventh month is completed.

Therefore, so far the person is 38 years and 10 months old

4. Calculate the number of days

There are 4 days from October 4 to October 8.

The person is 38 years, 10 months and 4 days.
