As we discussed in class, to express time on the hour, we say: -Son las dos. (It is 2:00.) -Es la una. (It is 1:00.)
To say what time something is at, we say: -A las dos... (At 2:00...) -A la una... (At 1:00...)
To express time on the quarter, half, and three quarter hour, we use the following expressions:
...y cuarto (quarter after) (:15)
Ex: Es la una y cuarto - It is 1:15.
...y media (half past) (:30)
Ex: Son las tres y media - It is 3:30.
...menos cuarto (quarter to) (:45)
Ex: Son las siete menos cuarto - It is 6:45. **
**When expressing times such as 6:45 in Spanish, we say that it is a quarter to the next hour. Ex: Son las siete menos cuarto. (It is a quarter to seven.) This is why we use seven instead of six.
