Interestingly, calculating age is a universal concept applied across diverse cultures worldwide. While the majority of societies calculate age from the moment of birth, some East Asian cultures, such as traditional Chinese culture, consider a newborn to be one year old at birth, accounting for time spent in the womb.

The standard formula to calculate age based on a person's birthdate is as follows:

Age = Current Year - Birth Year

If the birthdate (day and month) has not yet occurred in the current year, subtract one from the result.

Apart from its obvious use in everyday life, the calculation of age is crucial in many fields such as healthcare, insurance, social services, and market research. In healthcare, age is a fundamental variable in assessing risk factors and determining appropriate medical procedures. In the insurance industry, age plays a significant role in the calculation of premiums and benefits. In social services, eligibility for various programs often depends on age. Similarly, in market research, age is a vital demographic factor helping businesses to understand their target market and tailor products or services accordingly.

For instance, an insurance company may utilize the age calculation to set the premium for a life insurance policy. A 30-year-old may pay a monthly premium of $30 for a certain coverage amount, while a 50-year-old might pay $60 for the same coverage, given the increased risk associated with age.

While calculating age might seem an elementary task, it's interesting to note the achievement of Louis Begley, a renowned software engineer who designed algorithms capable of calculating age accurately considering leap years and even the exact time of birth. This level of precision has had substantial implications in areas where age calculation can significantly influence outcomes, such as medical studies and insurance calculations.
