In this article, we will explain how to calculate your age accurately using various methods, including manual calculations and online age calculators.

## Understanding the Basics of Age Calculation

Before we dive into the different methods of calculating your age, it’s essential to understand the basics of age calculation. Your age is simply the amount of time you’ve been alive, expressed in years, months, and days. Your age is determined by subtracting your birth year from the current year. However, to get a more accurate age, you need to factor in the month and day of your birth.

One of the most straightforward ways to calculate your age is by hand. All you need is a pen and paper, and you’re ready to get started. Follow these steps:

1. Write down your birth year.
2. Subtract your birth year from the current year to get the number of years you’ve been alive.
3. If your birthday has already passed this year, you’re done. If not, subtract one from the number of years you’ve been alive.
4. Write down your birth month and the current month.
5. If your birth month is after the current month, subtract one from the number of years you’ve been alive.
6. Write down your birth day and the current day.
7. If your birth day is after the current day, subtract one from the number of years you’ve been alive.

By following these steps, you should have a precise calculation of your age. However, this method can be time-consuming, and there’s always a chance of making a mistake.
