I have great difficulty in trying to explain about the difference between British style public holidays and Spanish style non working days without misusing the word holiday. The idea I have, entrenched with me since I was a lad, is that non working days are holidays. Easter Monday and May Day are holidays and the couple of weeks in Skeggy in July are holidays too. For Spaniards a holiday is a holiday and a day off work is a "festive" day. Amongst we Britons the idea of a public holiday is that it's a part of our holiday entitlement. So, if Christmas Day and Boxing Day, both of which are UK Public Holidays, fall on a Saturday and Sunday then we will get compensatory days on Monday and Tuesday. The Spanish idea is different. Spaniards have working days and non working days. Their "non working" calendar includes certain days and anniversaries which are national non working days - Constitution Day, All Saints, Good Friday plus some regional non working days decided by each Autonomous Community and, finally, a couple of local non working days which will be different in Pinoso to the local days in say Monóvar or Elda. If the day off falls on a working day, that's Monday through Saturday, then lots of people, won't have to go to work. If the non working day/anniversary falls on a Sunday then people won't have to go to work either. So, to a Spanish legislators way of thinking, the effect is the same. Last year for instance The day of the Valencian Community fell on a Saturday. The day was marked in the calendars as a non working day but, as most working people don't habitually work on Saturdays, it made absolutely no difference to the vast majority of working people in Alicante, Valencia or Castellón. They finished on Friday afternoon and went back to work on Monday morning. It was the same with Christmas day in 2021 and January 1st 2022 was another Saturday. Father's day is a National non working day but, in 2022, it will fall on a Saturday so most people won't really notice the difference - well, except for the meal. That's why neither Mother's Day nor Easter Sunday feature as "holidays" in Spain because Sunday isn't a working day. It also means that the public days off work vary from year to year.
This idea of finding an equivalent struck me the other day when someone asked me about their Suma. Suma is a tax collection agency that was set up by the provincial level government of Alicante back in 1990. It basically assesses, bills, collects and enforces local taxes for the municipalities in Alicante Province. Suma doesn't set the taxes, the local municipalities do. So, Pinoso, our town council, uses Suma to collect Road Tax and so does Sax Town Council but the tax for the same type of cars, the least environmentally friendly, is 154€ in Pinoso and 201€ in Sax. And there you have an example - I said Road Tax but that tax here is qualitatively different to the Motor Duty payable in the UK. The tax we pay here, el impuesto sobre vehículos de tracción mecánica, is a local tax that pays Town Hall wages, the fiesta fireworks and the Christmas lights rather than the upkeep of the nation. That's one of the reasons why, traditionally, there are a lot of toll roads in Spain. Actually with the ending of so many toll road contracts and the bankruptcy of others the National Government is considering ways to raise money for road maintenance from mileage type charges through to a general vehicle duty.
Now Suma doesn't collect in three of the five municipalities which share a border with Pinoso because they are in Murcia and the person who was talking to me lives in a village that "belongs" to one of those Murciano towns but which, generally, see Pinoso as being their town. It's not surprising that they use the shorthand of saying Suma when they refer to local taxes, "I've not got my Suma bill yet" or "When does the Suma bill come?" because, amongst other things, Suma is much easier to say than alcantillarado or exacciones municipales. Ah!, the joys of foreign living.
