A kiss is the common romantic gesture associated with midnight on New Year's Eve.
In many cultures, couples kiss when the clock reaches midnight as a symbolic way to begin the new year together. The gesture is often connected with hopes for affection, luck, and continuity in the months ahead. It is a social custom rather than a formal religious requirement.
The tradition has been reinforced by films, television, parties, and public celebrations. Large gatherings may show couples kissing at the stroke of midnight, while other people choose hugs, handshakes, cheers, or personal rituals instead.
The custom should not be confused with a universal rule about New Year's Eve. Practices vary widely by family, country, religion, and individual preference. Historical explanations also differ: some accounts connect New Year's kissing with older midwinter or masquerade customs, but no single origin story is accepted as the definitive source of the modern practice.
