It should fall on September 10 for most places so hopefully things are fine.

On a side note. Yes, this is a stupid tradition. Yes, it is a stupid religion. Yes, it was a tragic event. Does that mean that they need to adjust their stupid ideas around the tragic event? Example, I get up every morning and read the newspaper. It's a stupid tradition. There is nothing useful in a newspaper. It's not even entertaining. It is something I do as a personal tradition. If someone was brutally murdered by an early morning newspaper reader or for whatever reason early morning newspaper reading became associated with something bad, would you expect me to give up my habit? Would you be angry with me if I kept up my habit. It is my ritual and there is no reason you can expect me to give it up for some newborn taboo. Example 2, in mandarin there is a word that is very similar to the n word. Would you be unhappy with chinese people continuing to use that word despite all the shit that is associated with that word?

tldr: stupid rituals are a right. If their intention is not to insult, it is not an insult.
