Proper label for an annual event that skipped a year

Just like an essay, I will try to give you the prudent answer first: That is a fallacy.

On first thought, if anything, it would be the sixth annual. Literally, you only had six. Calling the sixth the seventh would be a lie. However, there is an exception. If it's annual, and on the sixth year, something happened, like a tornado, or logistical problems, that prevented the event from being hosted, then it would rightfully be the seventh.

One can probably imagine this event's website. This website would have a history section. Subsections would show 'year 1', 'year 2', and so on. 'year 6' would simply say that it the event was held, but fans who arrived would all know that hosting problems occurred.

If the reason was simply that people were lazy to do a sixth year or forgot, but not some unforeseeable intervention, then this whole thing is a fallacy. It is NOT the sixth year, nor the seventh year; it is the first year.

Think about dynasties or kingdoms. There was a kingdom, and a dynasty (or a lineage). It was conquered by a neighbouring kingdom. It was renamed 'Kingdom 2'. Then, some loyal followers of the first kingdom, wanted to restore the "original" dynasty. And so, they led a coup, re-instating one of the descendants of the king of 'Kingdom 1'. Now, irregardless of the new 'Kingdom 3' having more territory (as it is now combined), it still needs to be called 'Kingdom 3'. It is a new entity, as it had a break in between.

In your case, the break was simply not having an annual event, which is the fundamentals of something annual.

You can also use the organisation or language analogy. Like, once a language disappears from the face of the earth, because of ethnic cleansing, it is gone forever. However, I don't want to be redundant; I think you have gotten the point.

Sorry for explaining it in a philosophical way, but it is the only way; and, rightfully so! You asked this question - obviously - because it was a complicated issue; if not, it is because you didn't think it was as complicated, because not a lot of thinking was involved, which explains how you couldn't answer the question.

Thanks for asking the question, because it is indeed a meaningful concept, and I hope I didn't come off as rude.

Thanks!!!

Irregardless is not a word

COVID shutdowns have made this an issue for A LOT of events, including mine.
Looking at the essential purpose of calling it an "annual" event, it's because you're defining it as an event offered once a year on a regular basis. Everyone had to skip last year and maybe this year, but it's still on an annual schedule if you're normally doing it once a year. You're not saying how many times you've had it, that would simply be the number with out "annual."
In my case, it would have been the 11th year, but I still called it the "10th Annual" event because I'm saying "This event that is offered once every year, which people have liked enough for the last 10 times that you can plan on it being offered again this time next year."

Dyske, speaking of fallacies, your whole attempt to make a point failed the second you tried using the NON-word "irregardless." It doesn't make any sense.
