The keyword for 旬 is peak season. This kanji refers to a period of ten days, as the traditional Japanese and Chinese calendars divided each month into three ten-day periods. By extension, it came to signify the time when something—particularly food such as fruits, vegetables, or seafood—is at its freshest, most abundant, and most flavorful. It conveys the idea of optimal timing, when something is in its prime and most worth enjoying.
