133 years old.

The age of a little sixty-year-old is about 60 days today, so the age of a little sixty-year-old is about 133 years old today. There are roughly two reasons why the ancients called 60 years old the "year of sixty":

The first theory is that in ancient times, when there was no calendar, the calendar was calculated based on the heavenly stems and earthly branches. It is combined with 10 heavenly stems and 12 earthly branches to calculate calendar and time. After the heavenly stems and earthly branches are combined in pairs, the cycle is completed once, which is exactly sixty years.

Among them, the first among the Heavenly Stems is "Jia", and the first among the Earthly Branches is "Zi". With "Jia Zi" as the first unit, it is also called a Jiazi. And because the stems and branches are intertwined with each other, it is also called the flower armor. Sixty years is the cycle of sixty years, so sixty years later also became a synonym for sixty years old.

The second statement is mainly related to human body functions. Usually, white marks will appear at the roots of people's nails. As age increases, the body begins to age. By the time you reach the age of sixty, the body's metabolic function is gradually declining, and the white marks on the nails will also gradually decline. disappear. Therefore, the age of sixty is also called the "year of sixty."
