How do we translate the word 'fiesta' to English?

Good evening/morning, so a lot of fiestas are taking place right now in Spain. So what would be the closest word to 'fiesta' in English? Well ultimately some loss in translation is inevitable as a fiesta in Spain is a concept that is unique to Spain. Probably, the best word would not be 'party' for 'fiestas' happening in big towns or cities as the 'fiesta' really becomes quite sizable in big towns or cities. In these cases, the most appropriate word would be 'festival'. So Pamplona/Iruña has a bull running festival in early July. Valencia has a festival in March and San Sebastian de los Reyes similarly has a bull running festival in late August. If the 'fiesta' occurs in a village then we can safely name it a 'village party' since we do have village parties in the UK, albeit very different to those in Spain. Also, in the UK, a party can be at someone's residence or in a night club (discoteca). All the best.
