What it means
にかけて marks an approximate span that extends from one endpoint to another, usually in time or location. It is commonly used in the pattern “Noun 1 から Noun 2 にかけて,” meaning “from Noun 1 through Noun 2.” The endpoints are not always exact, and the expression emphasizes the area or period covered between them.
Usage note
にかけて normally follows a range with two endpoints, so it is different from にわたって, which emphasizes the duration or extent of one continuous span. It is also commonly written as part of から〜にかけて.
