Early forms of observance—especially in Gaul and parts of Spain—focused on both the Incarnation (or birth of Christ) and the Second Coming of Christ, core tenets of the Christian faith. The season was marked by a penitential attitude, in contrast to contemporary expressions of cheer. Varying regional differences converged into a standard tradition during the Middle Ages, which more closely linked the season to the Christmas story.
Today, Advent is observed with church attendance and the lighting of Advent candles on wreaths—one candle each Sunday, often associated with spiritual virtues like hope and joy, traditions established by Lutherans in 19th-century Germany. Beyond religious observance, the modern season is also defined by Advent calendars—many mass-marketed—that count down the days to Christmas.
