The only day of the week which has a name in Judaism is the Shabbat, which is named in the Torah (Exodus ch.31). Other days are simply called so-and-so-many-days-after-Shabbat.
The holy day of the week is called 'Shabbat' in Judaism, it starts sundown Friday and ends sundown Saturday.
The three days of the week most commonly considered days of worship are Friday, Saturday, and Sunday. Friday is observed as the day of congregational prayer in Islam, Saturday is the Sabbath for Judaism, and Sunday is traditionally the day of worship for Christians. Each of these days holds significant religious importance within their respective faiths.
7 is an important number in Judaism representing wholeness and completeness - so it probably isn't coincidental that there are 7 archangels and 7 days (and 7 Noahide commandments etc.). Some orthodox churches link the archangels with days of the week, but there doesn't seem to be much of a reason behind that.
Both "what days of the week" and "which days of the week" are correct; however, "which days of the week" is typically used when the choices are limited, while "what days of the week" is more open-ended.
Seven days in a week is more generally used than seven days in the week, except if in reference to a specific week such as 'the seven days in the week' when referring to a specific week, such as the week before Christmas.
