how do you know when to use o or a
I know that o is masculine and a is feminine such as nublado and nublada for cloudy, but sometimes some words don't seem to change, like la docena for dozen. I haven't seen it used as el doceno? should it be used that way?

Good question. The a and o endings refer to adjectives that agree in gender to what they are modifying.
However, docena is a noun, so it does not change. Make sense? BTW, welcome to SD. There are so many folks here who are happy to answer your questions.
Hi, and welcome to the forum. You are asking about adjectives here. Those that end in -o in the masculine change to -a in the feminine. Those that end in -e are invariable with respect to gender - they are the same for masculine and feminine. There are other adjectives which end in a consonant. Likewise, they are invariable with respect to gender. And example of such an adjective would be
popular.
Adjectives ending in -e, and those ending in a consonant, become plural by adding -s or -es, respectively. For instance:
inteligente, inteligentes
popular, populares
