12 and 21 both reduce to number 3
12 reduces to 3, and 21 also reduces to 3. This means both dates finally enter the Jupiter field of number 3.
The source does not stop at the final digit, though. The compound number remains important because it shows how the final number is reached.
The 12th route
The source treats 12 as Sun and Moon combining into 3, which differs from 21 because the leading digit is 1.
A person born on the 12th should therefore read the number 3 article, but should also keep the 12 compound route in view.
The 21st route
The source treats 21 as Moon and Sun combining into 3, which differs from 12 because the leading digit is 2.
A person born on the 21st should also read the number 3 article, while noticing that 21 arrives there through a different digit order.
Why digit order matters
The source gives importance to the first digit in a compound number because it places the date within a series. This is the main reason two dates can share a final reduced number without being read as the same.
In practical article reading, 12 and 21 should be compared through both the shared number 3 and the distinct compound routes.
Shared Jupiter number field
The number 3 chapter presents the Jupiter field through learning, discipline, counsel, planning, responsibility, ambition, generosity, and the wish to do meaningful or expansive work.
The shared reduced number means both dates should be read with number 3 themes, but the compound route helps explain why the two dates may express those themes differently.
How to use this comparison
Use this comparison after reading the exact date articles for the 12th and 21st. Then read the number 3 article to understand the shared planetary field.
For a fuller reading, compare the psychic number with the destiny number and name number rather than treating the birth date as the whole person.
