Morphology

brighten + one + days

The phrase is compositionally built from 'brighten' (to make lighter/more cheerful) plus 'one's day' (someone's day/mood), so the intended meaning 'make someone feel happier' follows directly from the constituents. This is a common, transparent metaphorical extension found in many languages and fits normal English patterns, so a B1 learner who knows the words would reliably infer the meaning.

Etymology

Brighten one's day paints a simple picture: a small light that brightens a person's day makes everything look sunnier, so a smile or kind act feels like that light. That's why it means 'to make someone feel happier'.
