Frida Kahlo Expo

My question is why if it's a holiday in Spain, the Mexican Consulate is closed? It's not a holiday in Mexico. And furthermore, why is their expo place closed?  These were the questions I asked myself when I tried to see the Frida Kahlo expo at the Mexican Consulate in Madrid. Why advertise if you are going to be closed to the public?

As a Mexican-American living in Spain, I was really surprised to find that this expo was closed. We found other Americans perplexed and complaining that they had come all the way to Madrid for this expo and now they didn't know what to do or where to go.

Of course living here for so long, I had a second plan, but I felt sorry for them.
