And then know the today date and divide into date, month year.Then divide your date of birth into the month, date and year.Without your birth date, you can not calculate your chronological age. I want to say again that chronological age depends on your birth date. This is very simple and you can calculate your chronological age easily. And now we will know that what is Chronological age formula by which you can calculate your chronological age. So all the years that he lives, the whole age is called his chronological age. And with the help of date of birth, you can calculate your chronological age, and you can find out how many years you lived.īasically chronological age is your original age.

The chronological age depends on your date of birth. Chronological AgeĬhronological age is the age which defines that How many old you are. And we will try to know what it depends on. For example, a child who was born on January 31 st in 2022 was 1 year old on January 31 st and 2 years old on February 1 st meanwhile, using the Gregorian calendar system, the child is only 1 day old.Firstly we try to calculate understand the chronological age. These are the dates at which a child's age would increase in these systems. For example, in 2022, the lunar new year occurred on February 1 st, while it occurred in February 12 th on 2021. For this reason, a child's age will increase at a different date (as measured by the Gregorian calendar) each year. Calendars that are purely lunar vary from solar calendars (like the Gregorian calendar) in that they are 11-12 days shorter than the solar year. Because months in a lunar calendar system are based on the monthly cycles of the Moon's phases, lunar months have different lengths than months based on the Gregorian calendar system. The age of the child increases at the turn of the lunar new year, rather than on their date of birth. While age in these countries is also measured using the Gregorian calendar, these countries additionally have their own separate measurements of age.Ĭhina & Taiwan-In both China and Taiwan, a child is considered to be 1 year old at birth using their traditional measurement of age. Three examples include age measurement in China, Taiwan, and Korea. Therefore, in certain extreme cases, such as a person being born 1 day before the turn of the new year, a person who is 1 day old as measured by the Gregorian calendar system may be considered 2 days old the next day in certain East Asian cultures. Additionally, rather than age increasing at their birthday, their age increases at the turn of the new year (either on the Gregorian or a lunar calendar). In certain East Asian cultures, rather than a person's age being measured in months for the first year of life, people are considered to be 1 year old at birth. While virtually everyone in the world uses this definition of age to some degree, certain cultures use other methods to determine chronological age. However, all of the above assumes that we are solely considering the most common measure of chronological age, which is based on a solar year and the Gregorian calendar, the most widely used calendar system in the world. To get even more exact by calculating hours and seconds, the exact birth time must be known, which is something that many people may not know offhand. This is slightly more complicated because the different number of days in a month as well as factors such as leap years need to be taken into account. To get an even more accurate age, we can take into account smaller increments of time than a year like months and days, as this calculator does. Most typically, a person's age is calculated by subtracting their birth year from the current year if their birthday has already occurred that year, then the result of the subtraction is their age if their birthday has not yet occurred, then their age is the current year minus their birth year, minus 1. The calculator can be used for any special occasion, such as anniversaries simply enter the date of the special occasion into the 'Birth Date' field to view the time since the occasion or until the occasion.Ī person's age is something that is seemingly simple on the surface, but can be confusing depending on their culture, or how they calculate age. It will also calculate the time difference between the current date and their previous or next birthday. This age calculator can be used to find a person's age given their birthday and a selected date.
