The word "Monday" derives from the word "moon." It is the "day of the Moon", "Moon Day" and, eventually, "Monday". This is not unique to the English language. The Romance languages also call that day the Moon's day. In Spanish, for example, Monday is "el lunes," meaning "the moon."
The Moon
The only day on which you generally do not see the Moon is on the day of the "new" moon, when the Moon is quite near the Sun in the sky. On any other day of the 29-day cycle, you will - weather permitting! - be able to see the Moon, either in the morning or in the evening.
