When will the year of the tiger be counted on the 20th10 of the lunar calendar?

February 4th is beginning of spring, which is a new solar term. February 10 is the first day of Geng Yin's New Year's Eve. If the child was born before the first day of New Year's Eve after beginning of spring, that is to say, the child should belong to a cow, not a tiger. The child was born on the first day of the second year and is already two years old. The old yellow calendar can understand at a glance. This has nothing to do with the zodiac.
