The Age Calculator is designed to instantly determine a person’s age or a range between two dates. Data calculated here is shown in seconds, minutes, hours, days, weeks, months, and years.
The ways of counting a person’s age differ in cultures around the world. The working principles of this online age calculator are based on several common age systems. As you can see, in the system represented here, age starts growing at one’s birthday. For instance, a person who’s lived for 4 years and 10 months is four at the moment, and they will turn five at their next birthday two months later. This age measuring system is common in most countries in the western world.
In certain cultures, people’s age is counted by years, with the present year being or not being included. For instance, a person who presently is thirty-one is of the same age as a person in their thirty-second year of life. According to one of the traditional age systems in China, children are born at the age of one; their age changes along with the Traditional Chinese New Year, and not on the actual day of their birth. For instance, if a baby is born one day before the Traditional Chinese New Year, just in two days, they will already be at the age of two, although they are only two days old.
Sometimes, the days’ and months’ result of the online calculator may appear to be rather confusing, particularly when the initial date falls for the end of a month. Here’s an example: everyone counts February 10 to March 10 to be one month. In fact, there exist two ways of calculating the age from February 28 to March 31. If we consider February 28 to March 28 to be one month, then the total result will be one month plus three days. However, if we take both February 28 and March 31 as the final date of a month, the result will be one-month sharp. Both results of the calculation are reasonable. In the calculation algorithm of our online calculator, we use the former method.
