为什么西方人会觉得13是个不吉利的数字，你造吗？

1. THERE WERE 13 PEOPLE AT THE LAST SUPPER.
“最后的晚餐”里有13个人。

And tradition has held that the 13th to take their seat was either Judas or Jesus himself.
传统的说法是：第13个落座的人不是犹大就是耶稣自己。

2. TRADITIONALLY, THERE WERE 13 STEPS TO THE GALLOWS.
依传统，上绞刑架要走13步。

According to popular lore, there are 13 steps leading up to the gallows. Gallows actually varied wildly, but even then, the number was often brought up to 13.
根据流行的传说，上绞刑架要走13步。实际上，绞刑架形式各异，但即便如此，也往往要凑出13这个数字。

3. WOMEN MENSTRUATE ROUGHLY 13 TIMES A YEAR.
女人一年大约来13次月经。

Some suggest that the association with 13 being unlucky is due to women generally having around 13 menstrual cycles a year (based on a cycle length of 28 days).
有人说13会和“不吉利”相关，是因为女人一年大致会经历13次月经周期（以每个月经周期为28天计算）。

4. A WITCHES' COVEN HAS 13 MEMBERS.
女巫集会有13位成员。

Although a coven is now considered to be any group of witches (or vampires, in some tellings), it was once believed that a coven was made up of exactly 13 members.
尽管现在人们认为任何一群女巫（有的说法是吸血鬼）都可以组成集会，但大家从前相信集会一定是13位成员构成的。

5. 12 IS A PERFECT NUMBER, SO 13 MUST BE UNLUCKY.
12是个完美的数字，所以13一定是不吉利的。

In some schools of numerology, the number 12 is considered to be the representation of perfection and completion. It stands to reason, then, that trying to improve upon perfection by adding a digit is a very bad idea indeed—your greed will be rewarded with bad luck.
在一些数字命理学流派看来，数字12代表着完美和完整。然后，由此推理出，想通过增加一个数字来提高完美的程度其实是一个很糟的点子——你的贪婪最终带来了坏运气。

6. ZOROASTRIAN TRADITION PREDICTS CHAOS IN THE 13TH MILLENNIUM.
索罗亚斯德教预言在第13个千禧年会有大混乱。

The ancient Persians divided history into four chunks of 3000 years. And although the exact timeframes can vary, some scholars feel that at the beginning of the 13,000th year there will be chaos as evil mounts a great battle against good (although good will eventually triumph).
古波斯人将历史分为4大段，每段为3000年。尽管准确的时间点会有所出入，但一些学者感觉1万3000年初就会出现混乱，邪恶势力崛起，与正义作对（尽管正义最终会取胜）。

7. 13 LETTERS IN A NAME MEANS THE PERSON IS CURSED.
名字由13个字母组成的人会受到诅咒。

There's an old superstition that says if you have 13 letters in your name, you're bound to be cursed. Silly, yes, but slightly more convincing when you consider that a number of notorious murderers' names (Charles Manson, Jack the Ripper, Jeffrey Dahmer, Theodore Bundy, and Albert De Salvo) all contain 13 letters.
有一种古老的迷信说法：如果你的名字里有13个字母，你就会受到诅咒。听起来很傻，但是想想那些臭名昭著的杀人犯的名字——Charles Manson、Jack the Ripper、Jeffrey Dahmer、Theodore Bundy和Albert De Salvo，这些名字里都有13个字母，这种说法也就稍微有些可信了。

8. SUPERSTITION HAS MADE FRIDAY THE 13TH TOUGH FOR BUSINESSES.
迷信导致逢周五的13号生意难成。

Friday the 13th is an expensive day for businesses. One analyst claims that around a billion dollars a year are lost as people choose not to do business of any kind on Friday the 13th.
从商业角度来说，逢周五的13号是很昂贵的一天。一位分析人士称，因为人们选择不在逢周五的13号做任何生意，每年大约损失10亿美元。
