The proper noun for “day” typically refers to specific days of the week or particular days that are named or significant. In English, days of the week are considered proper nouns when they are capitalized. These include:
- Monday
- Tuesday
- Wednesday
- Thursday
- Friday
- Saturday
- Sunday
These are all proper nouns because they represent specific days and are capitalized when written in a sentence.
However, “day” on its own is not a proper noun and is written in lowercase unless part of a title or the start of a sentence. For example:
- “I have a meeting on Monday.”
- “We will go hiking this Saturday.”
In summary, “day” is a common noun unless it is part of a specific, named day, in which case the name of that day (e.g., Monday, Friday) becomes the proper noun.
