About this pattern
Explanation
際に is used to specify the moment or situation in which something happens. It marks a point in time or a relevant context when an action or state occurs. It is common in formal or written Japanese and can refer to plans, instructions, or descriptions of events. Note that in many spoken contexts, speakers might opt for other time phrases, but 際に remains a reliable, precise option for describing moments like transitions, changes, or events.
