When should you capitalize the word 'afternoon'?

The word 'afternoon' should be capitalized when it is used as part of a proper noun or at the beginning of a sentence. For example, in the phrase "Good Afternoon, Mr. Smith," 'afternoon' is capitalized because it is part of a greeting and is being used as a proper noun. Similarly, if a sentence starts with "Afternoon," the word would be capitalized. However, in general usage, such as "I will see you in the afternoon," 'afternoon' is not capitalized.
