Saying the time.....

Saying the time.....
 

I lost my notes on time and the internet is giving me conflicting info.


Es la uno en punto = Is at 1:00 O'clock sharp!(used only for one O'clock)
Es a las dos en punto = Is at 2:00 O'clock sharp!

Son las tres de la tarde = Is(currently) 3:00 in the afternoon.


Are these correct?

Es la una en punto = It (the time) is 1 o'clock sharp/on the dot/exactly/to the minute.

Son las dos en punto = It (the time) is 2 o'clock sharp/on the dot/exactly/to the minute.

The question is: ¿Qué hora es?

As "hora" is feminine, numbers that refer to times are also feminine.

Only the article matches gender and number. For 1, the gender and number is feminine singular. For the rest, the gender remains feminine but the number is plural.
For 1, the ending must be changed to 'a' (to make it feminine). None of the other numbers used to tell non-military time take a different ending.

The OP's second sentence was correct. Es a las dos en punto. = It is at 2:00 o'clock sharp.

Ah! I missed that.

Based on the OP's suggested translation, it seems to me that the OP's first sentence should also have the preposition "a" and read "Es a la una en punto".

And I missed that. ;)
The English corrections I gave in my post equally apply to both of the OP's sentences.

I'm still a little confuse. I'll try to explain further(with the corrections).

The first one:
Es a la una en punto = I wanted this to say it is at, like a general shorthand if someone asks me when school starts, I wanted to e able to say "It is at 1:00 exactly"

The second sentence:
Es a las dos en punto= I wanted the same, but it is my understanding that if it isn't 1:00, then I have to say las because it is now more than one.

Are these bad ways of responding to someone? Do I have to announce that it is school I am talking about even though the other person has already mentioned the subject we are talking about?

The corrected sentences are correct.

If the subject is known, you don't have to mention it.
