Expresses a continuous range or span across time or space, from one point through to another. Unlike a precise from/until, it marks an approximate, blurred stretch where something happens throughout. Often used for weather, seasons, regions, or periods.

An approximate seasonal span, not exact dates
• Nuance: vague, continuous range — not a sharp start/end point. • Contrast with から~まで, which gives a definite boundary. • The verb usually describes something ongoing across the whole span.
The JLPT rarely asks whether you recognise a pattern — it asks which of several similar patterns fits. These are the ones ~から~にかけて is tested against.
から~にかけて marks a fuzzy, approximate span where the action occurs throughout; から~まで gives a clear, defined boundary with exact start and end points.
