Do you have to capitalize the word midnight in a sentence?

No, you don't have to capitalize "midnight" in a sentence.

Here's why:

* Midnight is a time of day. It's not a proper noun like a person's name or a specific location.

* Proper nouns are capitalized. However, times of day are not considered proper nouns.

Example:

* "We arrived at midnight."

Exceptions:

* If "midnight" is part of a title or a name, it would be capitalized. For example: "The Midnight Hour" or "The Midnight Sun."

* In some specific contexts, like poetry or literature, you might see "midnight" capitalized for artistic effect.
