Capital letters: 7 instances where using capital letters in English is grammatically correct
The rules for the use of capital letters are quite easy to remember. Generally, we use capital letters for proper nouns, which are the names of a specific person,place, or thing, and proper adjectives, which are usually derived (formed) from proper nouns. For example, Egypt is a proper noun (the name of a country), and Egyptian is a proper adjective, hence Egyptian pyramid must be capitalized.

We use capital letters for the days of the week, the months of the year but not for seasons.

The words sun, earth and moon can be both common and proper nouns. When used as proper nouns, they must be capitalized. In other words, our planet’s name is Earth, our moon is called the Moon, and our star is called the Sun. So, when referring to our moon, use the Moon or Moon. When referring to our sun, use the Sun or Sun.
