before dark

While sun's up

Before dark means before nightfall, while daylight remains: We need to get home before dark.

The phrase treats dark as a noun meaning the time when darkness arrives.

It implies a deadline set by nature rather than the clock, often carrying urgency about completing something while visibility or safety permits.
