The way we calculate a person’s age can vary across different cultures. This calculator uses the most common system, where a person’s age increases on their birthday. For instance, a person who has lived for 3 years and 11 months is considered to be 3 years old, and they will turn 4 on their next birthday, a month later. This system is widely used in most western countries.

In certain cultures, the age is calculated by counting years with or without including the current year. For instance, a person who is in their twenty-first year of life is considered to be twenty years old. In one of the traditional Chinese age systems, people are considered to be 1 year old at birth and their age increases at the Traditional Chinese New Year, not on their birthday. For example, if a baby is born just one day before the Traditional Chinese New Year, they will be considered 2 years old just 2 days later, despite being only 2 days old.

There can be some confusion when calculating the months and days of age, especially when the starting date is at the end of a month. For instance, we consider the period from Feb. 20 to Mar. 20 to be one month. But when calculating the age from Feb. 28, 2022 to Mar. 31, 2022, there are two possible outcomes. If we consider the period from Feb. 28 to Mar. 28 as one month, then the result is one month and 3 days. If we consider both Feb. 28 and Mar. 31 as the end of the month, then the result is one month. Both results are reasonable. Similar situations can occur for dates like Apr. 30 to May 31, May 30 to June 30, etc. The confusion arises from the varying number of days in different months. In our calculations, we use the first method.

How to Use Age Calculator ?

Using an age calculator is quite straightforward. Here are the steps:

  1. Input the Birth Date: Enter the birth date in the specified format (usually DD-MM-YYYY or MM-DD-YYYY). Some calculators also allow you to select the date from a calendar pop-up.
  2. Input the Current or End Date: This is the date until which you want to calculate the age. By default, this is usually set to the current date. However, you can change it if you want to calculate the age at a different date.
  3. Press the ‘Calculate’ Button: Once you’ve entered the dates, click on the ‘Calculate’ button.
  4. View the Results: The calculator will display the age in years, months, and days. Some calculators also provide additional information like the total number of days, weeks, or months lived.

Remember, the calculation method can vary slightly based on cultural differences in age calculation. For example, in some cultures, a person is considered to be one year old at birth, and their age increases at the start of the lunar new year, not on their birthday. So, the results from the calculator might differ based on these factors.
