Chinese Zodiac and Your Child's Birth Date: What It Actually Means
A baby is born into a year, and the year gives the child an animal. That is the part most families know. But the zodiac the family actually works with is a reading of the whole date, not just the year. This is what the year, the season and the hour each add to it.
The year is the frame
The animal of the year is the frame the child is born into, and it sets the broad shape of the family story. The dragon year, the tiger year, the rabbit year, each has a character that the family will tell for the next two or three decades. The frame is real, but it is not the reading. It is the setting, not the story.

The season is the weather
Within the year, the season a child is born in adds a second layer. A dragon born in the cold months and a dragon born in the hot months are two different dragons in the traditional reading. The season is where the birth card matters most, a card that carries the solar term of the birth date gives the season a shape, instead of leaving it as a vague summer or winter. This is the layer that most simplified zodiac reads skip, and the one that carries the most of the date.

The hour is the fine line
The hour of birth, in the traditional system, is the finest layer of all. It is the layer that two children born the same year and the same season can still differ on. For a birth card, the hour is what makes the card specific to the child, not to the year. A card without the hour is a card about the season, not about the child.

Before you order a card
Make sure the card you order carries the solar term and the hour of birth, not just the animal of the year. See the Name & Meaning category for the Solar Term Birth Card, digital and framed, which builds the reading from the full date rather than the year alone.
