There literally is one (or more than one) for every day. I was caught out by San Rafael last weekend (silly me!) which meant music in the square until 5am, and a slow, solemn procession as the saintly effigy was paraded through town the next day.
All lived to the full and thoroughly engaging the whole community - at least here in the old town where we live. It can be exasperating at times, but I wouldn't have it any other way.
