46년

I don't have sufficient context to write an accurate overview. The word "46" could refer to many different things (a year, a number, a designation, etc.), and you've only provided "year" as context, which isn't specific enough to determine which "46" you're asking about or why it would matter to a general reader. Could you clarify which "46" you'd like me to write about?
