high days and holidays
high days and holidaysspecial occasions. informal
In the Church's calendar a high day was the day of an important festival. A holiday (originally holy day ) was similar but less specific. Holiday now refers to any day off, without any sacred significance, and so holy day is used if a specifically religious occasion is intended.
