Generally, December 29th at the end of the year is called kunchi-mochi (mochi on the 9th) because of the sound 'ku-wo-tsuku' (literally, to pound nine, meaning to pound agony) and there is a custom of avoiding pounding and purchasing mochi only on this day among the several days at the end of the year and, on the other hand, in some areas, the 29th is welcomed reading 29 as fuku (happiness) taking another way of reading the numbers 2 and 9.
一般に年末の12月29日は「苦を搗く」音韻から九日餅（くんちもち）と呼び、年の暮れの数日間のうちその日だけは餅を搗いたり購入を避ける風習がある一方で二九を音韻からフク（福）と読み29日を迎える地域もある。
