Tikz calendar in spanish

Question

I've found this example and I'm trying to arrange the template to this year, my language and my country. My question is how can I get the days and months in Spanish. I've found this question in stackexchange, and and I've tried to apply the manner stated to rename the days and months, without success.

The code is:
