Age Calculator

Birthday, the most special occasion in every individual's life, marks existence in this materialistic world. Different countries celebrate birthdays in different ways that are associated with their culture. Even official holidays honoring the anniversary of the birth of historically significant individuals, such as national heroes or founders, are frequently observed on their birthdays.

Age Calculator

Well, there is this common problem we face while calculating age as it passes from one birthday to the other. Some calculate the birthday by saying plus one or minus 1, which always tends to create confusion among us.

Why confuse ourselves? We have this age calculator with us that will give the exact age based on the number of days preceding the last birthday.

The age or period between two dates can be calculated using the age calculator, which will mention Years, months, weeks, days, hours, minutes, and seconds will indicate the determined age.

In many cultures, a person's age can be measured in various ways. Universal way of calculating one's age has been incorporated in this age calculator and according to the calculator a person's age increases on their birthday. For instance, a person who has been alive for three years and eleven months is currently three years old, and they will become four on their next birthday, which is one month from now.

Japanese Age calculation

"Kazoe-doshi" is the name of a traditional Japanese age calculation method. This age calculation was once used but not anymore, as it was last used some 150 years ago.

Typically, we calculate one's age each time a birthday occurs. However, according to Kazoe-Doshi, a newborn is regarded as a year old when they are born because the first ten months of a person's life are also believed to begin during this time. As a result, it is possible to count yourself as one year older than your actual age when using Kazoe-Doshi. The Kazoo-Doshi approach placed a premium on the value of human birth. And at the New Year, everyone in Kazoe-Doshi gains a year to their age.

Chinese age calculator

Based on western system of counting age from birth, the Chinese system starts to count the age right from pregnancy. The child's age is regarded as one year at the moment of birth because the length of pregnancy can differ. In the ancient Chinese system of age calculation, the age increases by one year on Chinese New Year rather than on the birthday day.

In the Chinese calendar, there are fewer days in a year. When we compare English calendar with chinese calendar, a 24 year-old person from America will be 26-year-old person according to chinese calendar

E.g., If a kid is born one day before the Traditional Chinese New Year, they will be two even though they are just two days old two days later.

Age is determined using two ways

This age calculator determines age using two similar yet slightly different approaches.

  • This technique expresses age in years, months, and days in addition to months and days.
  • The alternative approach is where the age is calculated only based on the total number of days.

While calculating age, one must always remember that all months don't carry the same number of days, as normal years have 365 days, whereas a leap year has 366 days.

Here in this age calculator, age is calculated based on years, and they give it in common terms.

E.g., A 15-year-old boy will mention his age as 15 and not as 12 normal years plus three leap years.

Although we know that years might vary in length, we generalize between regular and leap years and treat them equally in this age calculator. And the same is true for months-old born babies.

The age calculator determines age by treating all years and months equally, which is universally understood.

One needs to add extra few days in leap years just to find how long the person has been alive.

Additionally, you must be aware of the total number of months with 31 days, 30 days, and 28 days.

This age calculator calculates one full day after the start day just by assuming zero as the start date. A total age of 3 days will be returned, for instance, if the dates 1/07/2023 and 1/10/2023 are entered into the calculator. Day 1 is on Saturday, Day 2 is on Sunday, and Day 3 is on Monday. The tenth day is not included in the number of days.
