What is the best time for harvest?

I'm curious, could you please elaborate on the optimal timing for harvest? Is there a specific season, month, or even day that is considered the best for maximizing yield and quality? Are there any factors that should be taken into consideration, such as weather patterns or the maturity of the crops? I'm eager to learn more about the science behind determining the best time for harvest and how it can impact the overall success of a farming operation.
