When was daoism?

AnswerI don't know when Daoism was founded, but I know when Laozi was born. He was on September 14th 604 BC in the country of K'u in the kingdom of Ch'u. AnswerTaoism was founded by Lao Tzu (Laozi), who is thought to have lived sometime during the fourth, fifth, or sixth centuries BC. There is no record of precisely who he was, and there is no reference to him older than about the beginning of the first century BC. Traditions place him as a contemporary of Confucius, who lived from 551 to 479 BC, but some historians date him much later.

According to legend the Tao Te Ching was written as he was retiring at a very old age, and this act is considered the founding of Taoism.
