折には

折には is a formal, literary way to refer to a specific occasion or moment. It marks the time frame for what follows and is often used in writing, speeches, or polite conversation. The pattern typically attaches to a noun phrase (Xの折には) to indicate “on that occasion of X,” or uses 折には by itself to introduce a statement about what should be done, what happens, or what is customary at that particular time. Note that it has a slightly old-fashioned or formal nuance compared to more everyday phrases like その時 or その折、 and is commonly found in written Japanese or formal speech.
