Questions & Answers about ¿Qué fecha es hoy?
Why do we use es instead of está for the date?
Even though the date changes every day (which might make you think of the "temporary" verb estar), Spanish always uses the verb ser (like es) to talk about dates, days of the week, and time.
If someone asks me this, how should I answer using the dates I'm learning?
You can answer by saying Hoy es... (Today is...) followed by the formula el [número] de [mes]. For example, you would reply: Hoy es el cuatro de octubre (Today is October 4th).
Why doesn't it say something like "la fecha de hoy" to mean "today's date"?
Why do we use Qué instead of Cuál here?
In Spanish, when a question word comes directly before a noun (like the word fecha), you almost always use qué, which translates to "what" or "which." So, qué fecha simply means "what date."
