The name 'Montag' (Monday) comes from the words 'Mond' (moon) and 'Tag' (day). So it literally means 'Tag des Mondes' (day of the moon), just as 'Monday' in English means 'moon's day'.
Früher orientierten sich die Menschen am Mond.
In the past, people oriented themselves by the moon.
To express a point in time on a specific Monday, you always use the preposition 'am' (an + dem, on).
Wir haben am Montag eine wichtige Besprechung.
We have an important meeting on Monday.
If you want to describe a regular, recurring action that takes place every Monday, you add an '-s' and write the word in lowercase: 'montags' (on Mondays).
Montags gehe ich immer zum Sport.
On Mondays I always go to sports practice.
'Montag' (Monday) is often combined with other time expressions to specify the time more precisely. Common combinations are 'am Montagmorgen' (on Monday morning), 'nächsten Montag' (next Monday), or 'jeden Montag' (every Monday).
Ich rufe dich nächsten Montag an.
I'll call you next Monday.
Tuesday
'der Montag' and 'der Dienstag' are both weekdays right at the beginning of the week. They are easy to confuse because they come directly after one another. 'Montag' is the day after Sunday and often the first working day. 'Dienstag' comes after that, so it is between Monday and Wednesday. A practical tip: first comes Monday, then Tuesday.
