How it's used
Primarily used in formal or professional contexts, such as describing the opening of a store, a movie release, or the start of a new job. It carries a slightly more serious or official tone compared to simply saying 第一日. While it functions as a noun, it often appears in news headlines or formal announcements to denote the commencement of an event.
Examples
This movie was already sold out on its first day of release.
Remember to arrive early on your first day of work.

Common mistake
Learners often use it interchangeably with 第一日 in casual conversation, but it can sound overly formal or stiff when talking about personal events like your first day of school or a holiday.
