What is the primary purpose of a daymark (unlighted ATON)?

Explanation:
Daymarks provide a daytime visual reference for navigation. Because they’re unlighted, they don’t emit light or signals at night. Their main purpose is to give mariners a clear, recognizable visual cue during daylight to identify a location, align with channels, and help determine position on the chart. At night you’d rely on lights, fog signals, or other radio or radar aids, not a daymark.
