What is the name of the New Year's Eve service in which Buddhist monks in South Korea ring a bell 33 times?

The Bosingak bell-ringing ceremony is Seoul's New Year's Eve service in which a large bell is rung 33 times.

Bosingak is a pavilion and bell in Jongno, central Seoul. On New Year's Eve, a public ceremony is held around the bell, with the ringing forming the symbolic center of the midnight celebration. Seoul's mayor and other invited participants commonly take part alongside Buddhist monks and civic representatives.

The 33 strikes are linked to the traditional Buddhist view of the heavens. In Korean cultural interpretation, the ringing is associated with welcoming the new year and wishing for peace and prosperity. The ceremony is a modern public event connected to a historic city bell, rather than a direct reenactment of one uninterrupted medieval countdown.

The Bosingak bell has been associated with Seoul's daily timekeeping tradition. The current bell was cast in 1985 after the earlier historic bell was preserved, and the pavilion became a recognizable landmark for the capital's New Year's observance.
