Explanation:

[STC0010928]. “The halcyon days of youth” is an expression that uses the word “halcyon” to refer to a time of happiness, wealth, success, or peace. The term “halkyn” was used to refer to kingfisher birds in ancient Greek mythology, which is where the term originated. According to an old myth, the god of the wind was overjoyed with these birds so much that he caused a period of peace to reign over the oceans while they nested. This peace lasted until the birds’ eggs successfully hatched. This myth eventually led to the word ‘halcyon’ being used in a more generic sense to signify ‘calm.’
