The days and "on Monday"
Explanation
The days of the week always take a capital letter: Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday. The key rule is the preposition of time. Use ON for days: I have class on Monday, I rest on the weekend. Use AT for clock times and night: at nine, at night. Use IN for parts of the day and months: in the morning, in the afternoon, in July. A common mistake is "at Monday" or "in Monday" — with days it is always ON. To ask the day: What day is it today? — Today is Wednesday.
Examples
- What day is it today? — Today is Wednesday.What day is it today? — Today is Wednesday.
- I have class on Monday and Thursday.I have class on Monday and Thursday.
- Tomorrow is Friday. The weekend!Tomorrow is Friday. The weekend!
- I rest on the weekend.I rest on the weekend.
