A Daywalker is a person who can speak the truth objectively without condemnation or prejudice against other people's ideas; a person who can "walk in the light of truth" without fear of reprisal or oppression; a writer or blogger who uses their real name to publish their opinions.

Daywalker also refers to people with red hair (referred to as "gingers" in Great Britain) who do not have freckles and people with very pale white skin who are able to go outside in the sunlight without getting burned. A Daywalker is also a fictional reference to a vampire that is half-human who has all of the strengths of a vampire with none of their weaknesses. The character of "Blade" in the movie and Marvel comic series was a Daywalker.
