Day of the month

Born on the 13th — what the day of the month means

The 13 reduces to 4: that is the day number, and it is the same whatever month and year you were born in.

What the 13th becomes in each month

The birthday number is the day number added to the month number and reduced. It is the part of a Life Path that does not depend on the birth year, so everyone born on this day of that month shares it.

Being born on the 13th

The thirteenth gives a four by way of a one and a three: initiative and expression brought into a structure. People born on the 13th usually build something of their own and do it methodically rather than in bursts — the habit of writing things down, costing them and checking them appears early. The number carries a load of superstition in the culture; in the arithmetic it behaves as an ordinary four and has no separate meaning at all. The limit is the standard one for a four: change is hard and needs preparation time.
