How do you say the fifth hour sixth seventh and eighth in spanish?

The Spanish doesn't directly translate the ordinal numbers (first, second, etc.) in the way English does for telling time. Instead, you use cardinal numbers (one, two, etc.).

* Fifth hour: la cinco (literally "the five")

* Sixth hour: las seis (literally "the six")

* Seventh hour: las siete (literally "the seven")

* Eighth hour: las ocho (literally "the eight")

Note the use of "las" (the feminine plural article) for hours six through twelve. "La" (the feminine singular article) is used for one to five.
