The phrase "to date" should not be hyphenated. It is commonly used as an adverbial phrase meaning "up until now." When used in this context, it remains as two separate words. However, if used as part of a compound adjective before a noun (e.g., "to-date information"), it can be hyphenated.
No, "attorney general" should not be hyphenated. It is a noun phrase where "attorney" serves as a modifier for "general," and in standard usage, it is written as two separate words. Hyphenation is not necessary in this case, as the phrase is widely recognized and understood without it.
The term "all day" is not hyphenated when used as a standard phrase, such as "I worked all day." However, when used as a compound adjective before a noun, it can be hyphenated, as in "all-day event." Always consider the context to determine the correct usage.
No, "year long" is not hyphenated when used as an adverbial phrase, such as "The project will last year long." However, when used as a compound adjective before a noun, it should be hyphenated, as in "a year-long project."
