In general, you should look out for major religious holidays when planning things. That is what is called "Good planning." Yes, it may be cheap to run a big conference over Christmas... But will you get the attendance you want? If you want Jews to attend your conference. (Probably not unreasonable in the tech sector.) Not putting your event over the high holidays is smart, same as not putting it over the Easter holidays is smart if your want Christians to show up. As someone who has gotten this wrong, by planning over EASTER. Yeah, I did replan. And if I was told I'd planned over the high holidays, I'd re-plan, especially if there were 2 other valid dates I could use, which the article says. As far as pastafarians, I honestly don't know, but when you work with India, with many major holidays, you HAVE to be on top of this stuff, for their holidays. If I was planning a conference with a large number of pastafarians attending, you know what... I would take their needs into account! It isn't insane. It is good business.
