見十齋條。
(十齋) The ten 'fast' days of a month are 1, 8, 14, 15, 18, 23, 24, 28, 29, and 30. In certain periods flesh was forbidden on these days, also all killing, hunting, fishing, executions, etc.
十個行持八齋戒的好日子,即每月之一日、八日、十四日、十五日、十八日、二十三日、二十四日、二十八日、二十九日、三十日。据地藏經說,以上十日是諸罪結集定其輕重的日子,若人能於此十齋日對著佛菩薩的聖像讀誦地藏經一遍,則東西南北百由旬內,無諸災難。
