How to Calculate Age

Calculating age is a common task that involves determining the time elapsed between a person's birthdate and the current date (or any specified date). This calculation is useful for various purposes, including legal matters, healthcare, and personal milestones.

Formula and Components

The basic formula for calculating age is:

\[Age = Current Date - Birthdate\]

Where:

• Current Date is the date for which we're calculating the age
• Birthdate is the person's date of birth

Calculation Steps

1. Determine the birthdate and the current date (or calculation date).
2. Subtract the birthdate from the current date.
3. Express the result in years, months, and days.
4. If needed, convert the age to other units (total months, days, or seconds).

Example Calculation

Let's calculate the age of someone born on January 15, 1990, as of June 1, 2023:

1. Given:
   Birthdate: January 15, 1990
   Current Date: June 1, 2023
2. Subtract the dates:
   June 1, 2023 - January 15, 1990 = 33 years, 4 months, 17 days
3. Convert to other units:
   Total Months: (33 × 12) + 4 = 400 months
   Total Days: Approximately 12,191 days
   Total Seconds: Approximately 1,053,302,400 seconds
