The Indonesian phrase "11 september 2025 berapa hari lagi" functions as an interrogative adverbial phrase of time. Its primary grammatical role is to pose a direct question seeking a specific quantity of time (days) remaining until a future date. The phrase does not belong to a single part of speech like a noun or verb but is a complex construction that operates as a complete interrogative unit. The core of the phrase is the interrogative determiner "berapa" (how many), which modifies the noun "hari" (day) to inquire about a numerical duration.
A detailed grammatical analysis reveals four key components. "11 september 2025" is a noun phrase functioning as a temporal locator, establishing the specific endpoint in time. "Berapa" is an interrogative determiner that initiates the query for a quantity. "Hari" is a noun that specifies the unit of time being measured. Finally, "lagi" is an adverb meaning "more" or "remaining," which frames the query relative to the present moment. The syntax combines these elements to form a cohesive question: [target date] + [interrogative quantifier] + [unit of time] + [adverb of remaining duration].
In a practical context, particularly as a digital search query, the phrase transcends its purely grammatical classification to become a functional command. Its semantic intent is to request a calculation. A system processing this input would interpret it not just as a question but as an instruction to compute the difference, in days, between the current date and September 11, 2025. Therefore, while its part of speech is an interrogative phrase, its application is that of a computational query seeking a precise numerical value.
