Calennig is a Welsh New Year's tradition where children, and sometimes adults, visit their neighbors and friends to give them small gifts such as sweets, fruit, or coins. This is usually done on New Year's Day or the night before, and it's a way to wish the recipients good luck for the year ahead.
The word "calennig" comes from the Welsh word for "New Year's gift", and it's been a part of Welsh culture for centuries. The gifts given during calennig are usually wrapped in paper or cloth and sometimes decorated with ribbons or flowers to make them look pretty.
This tradition is kind of like trick-or-treating at Halloween, but instead of asking for candy, the children give gifts to people they know. It's a way to show kindness and appreciation to others, and it's also a fun way to celebrate the New Year.
So, the next time you hear someone talking about calennig, remember that it's a Welsh New Year's tradition where children give gifts to their friends and neighbors to wish them good luck for the year ahead.
