“Day” and “daytime” are the clearest opposites of “night.” Other useful contrasts identify specific daylight periods or the transition from darkness into light, so they are related temporal contrasts rather than exact antonyms.

Noon

Sunlight

Broad daylight
Broad daylight emphasizes full daytime visibility, often in contrast to darkness or secrecy.
Example: The theft happened in broad daylight.
Waking hours
Waking hours contrasts with night when night is being associated with sleep rather than darkness alone.

Light

Daylight hours
Daylight hours is a practical phrase for the portion of the day with natural light.

Use Day for the Direct Opposite
If the sentence simply contrasts night with its temporal opposite, day or daytime is usually best. Dawn, morning and noon identify narrower periods, while daylight, sunlight and first light emphasize illumination rather than the calendar day.
