The use of the phrase "The Golden" likely comes from Japanese Prime Time TV. Prime time is 7pm to 11pm, and within that 4 hour block, 7pm to 10pm specifically is Golden or Golden Time, and it's supposedly when the most people watch TV. (I imagine this statistic has changed since Persona 4 came out due to recordings and streaming and whatnot?)
Notably, this time period doesn't include late night (midnight) viewership.
