All Daily and Seasonal Light Cycles

This group collects the Meteorology subcategory's members that name a recurring point or period in the daily or seasonal cycle of daylight: dawn, sunrise, the golden and blue hours, dusk, sunset, twilight, an eclipse and the terminator line dividing day from night, along with the false sunrise and false sunset that a mirage can produce. These are defined by their position in a recurring cycle of light rather than by a physical optical mechanism, which is what separates this group from the subcategory's Atmospheric Optical Phenomena group.
