On this day in 1986: Li Wenliang was born, one of the first Chinese doctors to sound the alarm on Covid19 and to die from the disease.

it changes the age, but not the date of birth.

If you were Chinese and born October 3rd 1985, on October 3rd of 1995, you would be 11, because on the day of your birth you are 1 years old.

in France, you'd be 10 because on the day of your birth you're 0 years old.

ain't no thing.
