"I like December."

[Christina131184]

Ο Δεκέμβριος μου αρέσει is not okay?

[Stefan_Chirila]

Μου αρέσει Δεκέμβριος - is not correct? Why?

[jaye16]

In Greek the definite article is used with almost all nouns. So, here you needed "Μου αρέσει ο Δεκέμβριος". I've added the whole phrase to the drop down hints to avoid other problems.
