にかけて

The grammar structure にかけて is used to express a range or span – typically of time or space – meaning "over," "through," or "from ... to ..." It indicates that something occurs, extends, or continues across a certain period or area. It is most common in the pattern 〜～から〜～にかけて.

Time range

When describing a span of time, にかけて indicates that something happens over or throughout that period. Unlike 〜～からから～まで, which marks precise start and end points, にかけて implies the boundaries are approximate or gradual.

Spatial range

When describing a physical area, にかけて indicates that something extends across or spreads over a region.

Key nuances

• にかけて emphasizes that the boundaries are not sharply defined. The phenomenon may not start or end exactly at the stated points.
• It is used in weather forecasts, news reports, and formal descriptions, but also appears in everyday conversation.
• The particle から often precedes にかけて to mark the starting point, forming the pattern ～から～にかけて.
• Do not confuse this with 〜～にかんして関して ("regarding/concerning"), which is a different expression entirely.
