Illanhämärä

Illanhämärä refers to the twilight period that occurs after sunset. It is the time when daylight gradually fades and the sky transitions from bright to dark. This period is characterized by dim light and is often associated with a peaceful and serene atmosphere. The duration and intensity of illanhämärä vary depending on geographical location, season, and atmospheric conditions.

During illanhämärä, the sun is below the horizon, but its rays still illuminate the sky. This phenomenon is known as civil twilight, nautical twilight, or astronomical twilight, depending on how far below the horizon the sun is. Civil twilight is the brightest phase, where sufficient light remains for most outdoor activities. Nautical twilight is darker, and astronomical twilight is the darkest, when celestial navigation becomes possible.

Many cultures and traditions have associated illanhämärä with specific meanings or activities. In some societies, it is a time for reflection, prayer, or quiet contemplation. In folklore, it is sometimes considered a mystical period when the boundaries between the natural and supernatural worlds are believed to blur. The visual spectacle of illanhämärä, with its changing colors and soft light, has inspired artists, poets, and writers throughout history. The term itself is of Finnish origin, combining "ilta" (evening) and "hämärä" (dimness or twilight).
