Ask when a library opens and say how long a class lasts.
The idea
Hora means hour or clock time and is feminine: una hora, dos horas. Use a la una for one o’clock and a las dos for two o’clock.
Examples
- ¿Qué hora es?What time is it?
- La reunión empieza a la una.The meeting starts at one.
- El tren sale a las dos.The train leaves at two.
- La clase dura una hora.The class lasts one hour.
- Esperamos dos horas.We wait for two hours.
- ¿A qué hora abre la biblioteca?What time does the library open?
