As a person
Born on the 28th, or a 28/1 life path. These are two separate wealth signals.
Weak spots: family ties, close relationships and a tight grip on money.
A 28 may plead poverty while being better off than you.
As a day
The 28th: buy a wallet, get a haircut, list or price property, found a company, start money projects.
Skip a 28th whose total is unfriendly to you, such as a 7 day.
28 June and 28 August work less well than other 28ths.
As a year
A 28/1 year is a 1 year: start new things.
Friends and enemies
As a 1. Friends: 7 and 11. The 8 looks after a 1, one way. 3 gets on with a 1.
As a 1. Enemy: 9, the worst pair in numerology.

Enemy numbers
Compounds
2+8 = 10, then 1+0 = 1, so 28 reads as a 1. Every 1 line applies to it.
The 2 and the 8 turn the 1's drive toward money.
