Generally, age of a person is the time passed since the birth of a person in terms of years. When a baby is born, it is known to be at the age of zero. After completing 12 full months, its known to be at age 1.
In the international age system, the age is calculated by counting each chronological full year passed since the birth of a person. But some nations such as China and Korea accept a newborn baby is 1 year old rather than begining with age '0' (East Asian Age Reckoning). In Asian age reckoning, counting of age starts from the time of pregnancy. So the age of a newborn person is '1' and the age is incremented on Chinese New Year (Traditional Chinese Lunar Year). This may lead to a big difference, for example if a person is born the day before the Chinese New Year, baby is accepted to be at the age '1'. After the Chinese Lunar New Year, age turns to 2 where the baby is actually 2 days old only. Asian reckoning is initiated in China but less common these days due to official matters. These cultures seems to be migrating to western age system to eliminate differences globally.
