When we talk about the past with fondness, we often use the phrase "the good old days". However, there are many other synonyms to describe the same sentiment with more nuance. For example, we could use "nostalgia" to evoke a longing for a time past, or "golden age" to emphasize a period of particular prosperity or bliss. "Halcyon days" similarly connotes a time of peace and tranquility, while "yesteryear" and "days gone by" evoke a sense of the passage of time. Ultimately, the phrase we use to describe the past can reveal much about our own personal and cultural perspectives, and the way we view history and progress.
