Birthday number, in full
Of the numbers in a standard reading, this is the least ambitious and the easiest to check. It ignores the month and the year completely and looks only at the day of the month. Practitioners treat it as a narrow claim: not who someone is, but one thing they are unusually good at, sitting inside the wider Life Path reading rather than competing with it.
Reduce the day and you get the number. On this site master numbers are preserved, so the 29th gives 11 and stays there, while the 11th and the 22nd never move at all. That leaves a smaller set of birthday numbers than the 31 days might suggest, with several days sharing each one. Anyone born on the 7th, the 16th or the 25th ends up on 7.
Many practitioners keep the unreduced day alongside the digit, on the reasoning that the 4th, the 13th and the 31st all reduce to 4 but are given different shades. The 13th in particular gets attention, because 13 is one of the totals some schools flag as a karmic debt. Confusing the Birthday number with the Life Path is the common mistake, and the difference is simply how much of the date gets used.

A worked example
Someone born on the 25th adds 2 + 5 = 7, so the Birthday number is 7, shared with everyone born on the 7th and the 16th. Born on the 29th, 2 + 9 = 11, and this site stops there rather than continuing to 2, because 11 is a master number. The 31st gives 3 + 1 = 4, which puts it alongside the 4th and the 13th.

Birthday number: frequently asked
Scope. The Life Path uses the whole date. The Birthday number uses the day of the month and nothing else, which is why someone born on 25 December 1988 and someone born on 25 March 2001 share a Birthday number of 7 and have Life Paths with nothing in common.
On this site, yes. The 11th and the 22nd stay put, and the 29th becomes 11 and stops. Other calculators reduce those to 2 and 4.
