Monday: the Moon’s Day
Monday is the first day of the week according to the international standard ISO 8601, but in the US, Canada, and Japan, it's counted as the second day of the week.
Monday comes after Sunday and before Tuesday in our modern-day Gregorian Calendar.
The English word Monday is derived from Old English and means “the Moon's day.”

First or Second Day?
According to the international standard ISO 8601, Monday is considered the first day of the week. Most European countries' calendars show Monday as the first day of the week. However, in many cultures and languages, Monday is given a name that means either “second day,” marking Sunday to be the first day of the week, or a name that means the day after Sunday.

“I Don't Like Mondays”
In many cultures, Monday is considered the worst day of the week because it is the first day of the workweek. Song lyrics often feature Monday as a day of depression, anxiety, or melancholy such as “Monday, Monday” by the Mamas & the Papas in 1966 or “Rainy Days and Mondays” by the Carpenters in 1971, not to mention “I Don't Like Mondays” by the Boomtown Rats in 1979.
However, Mondays are considered good days for fasting in Judaism and Islam. In the Eastern Orthodox Church, Angels are commemorated on Mondays.
