The Spanish phrase "11 sep 2001 que dia de la semana fue" is an interrogative sentence that translates to "September 11, 2001, what day of the week was it?" The grammatical core of the query is the noun phrase "que da de la semana" ("what day of the week"), which seeks to identify a specific temporal attribute of the date. The definitive answer to this query is that September 11, 2001, was a Tuesday.
An analysis of the phrase's components clarifies its function. "11 sep 2001" is the subject date, with "sep" being the standard abbreviation for "septiembre" (September). The verb "fue" is the third-person singular preterite indicative form of the verb "ser" (to be), correctly used for expressing a state or identity in the past. The question is constructed around the interrogative determiner "que" (what/which), modifying "da" (day). The day of the week can be determined using a perpetual calendar, a computational algorithm such as Zeller's congruence, or by consulting any standard digital or historical calendar for that year.
The practical application of this question is to establish the temporal context for the significant historical events that occurred on that date. Knowing the specific day of the weeka Tuesday (in Spanish, "Martes")anchors the events within the framework of a standard workweek, which is a crucial element in understanding the timeline and impact of the day's attacks. Therefore, the phrase is a request for a factual data point that provides context for a major historical event.
