what is the difference between a las and son las when telling the time
....but be careful to speak of one o'clock in the singular. Well, sorry, you probably already know that.
What I do not know is whether one speaks of "la" una or "el uno" -- "a la una" o "al uno", "es la una" o "es el uno". - or something entirely different.
I guess that it must be "la una" because it is "a las xxx" and "son las xxx". I will try to look this up in my textbook. And I will look up "hour" to see what is its gender because that is probably what governs this use.
thank you at 7 oclock and it is 7 oclock
You're correct. They are all las..xxx horas.
Son las tres (horas). That's probably why time is translated as hora. ¿Qué o Cuál es la hora? ¿A qué hora es'
