I have never heard of 7 being a lucky number in western culture and your link doesn't support that. 3 is a lucky number, 13 is an unlucky number, 7 is nothing to me.

So I don't think its that, 7 is still a very common "random number" here even though there is no special cultural significance to it.

Have you heard of Las Vegas? The 777 being the grand prize? Maybe it is not universal to all of western society but I have never before today heard of a culture where 3 was the lucky number. The USA’s culturally lucky number is absolutely 7.

I don't live in USA, the west includes Europe. 7 is maybe a lucky number in USA but not where I live. So I think that would be more of an American thing than a western thing maybe. Or maybe its related to some parts of Christianity but not others.

I’ve heard 7 as lucky all my life in the US and it’s mentioned in the Wikipedia page for 7. I think if you asked the average English-speaking American to name a number thought of as lucky most people would say 7.

Lucky Seven/Lucky Number Seven is also just a common phrase in American culture. There’s even a Wikipedia page of things called Lucky [Number] Seven. https://en.m.wikipedia.org/wiki/Lucky_7

Some sustain that 7 is the God's number, stemming from "God created the world in seven days"[1]

Also, _"According to some, 777 represents the threefold perfection of the Trinity"_ [2]

It's definitely used in slot machines as a lucky number. Which came first I'm not sure (but I suspect from a sibling comment in the same thread it's based on perceived commonality and primeness historically and became "lucky" in the past because of that).

While I have never heard of someone referring to 7 as a lucky number, 7 is the most common sum of two rolled dice. So I can see how people would regard it as a lucky number. Along the same lines, I assume that someone who mentions 42 as a random number has at least some interest in science fiction.

You must be living under a rock if you’ve never heard of 7 as a lucky number.

I prefer to calculate with numbers, and don't pay much attention to superstitions around them. I don't gamble, nor much pay attention to conversations about gambling, so I pretty much ignore any mention of lucky numbers when such topics arise (aside from knowing that some people have lucky numbers). If you refer being isolated from a particular aspect of life living under a rock, so be it. Though I will point out that I like wide open space. I'm more of an astronomer than a geologist!

I have never heard of 7 being lucky until this thread.

I think you overestimate how cultural diverse western countries are when it comes to small things like this.

Hmm really? Even on the Wikipedia page for 7 (https://en.m.wikipedia.org/wiki/7), one of the first things it says is “7 is often considered lucky in Western culture and is often seen as highly symbolic.” And FWIW you can see the Wikipedia edit history, that isn’t a recent edit, nobody here is messing with it :)

“Lucky Number 7” is a common phrase, there was even a popular movie that played on this, “Lucky Number Slevin” (https://m.imdb.com/title/tt0425210/). It’s one of the first numbers I’d think of as a “lucky number.”

It's associated with Christ by several Protestant Christian denominations.
