Why does advent go for 24 days?

Advent traditionally lasts for four Sundays leading up to Christmas, but it often spans from late November to December 24, totaling 24 days. This period signifies a time of preparation and anticipation for the celebration of Christ's birth. The focus is on spiritual reflection, prayer, and the themes of hope, peace, joy, and love, culminating on Christmas Eve. The 24-day structure has also influenced the popular Advent calendar, which counts down to Christmas Day.
