There are posted later in the month. Don't post a new copy on the 1st. The most recent is here: https://news.ycombinator.com/item?id=49686380
(n=1, ymmv)
IMO if there isn't a schedule, then posting it on the 1st sounds good.. since that's when the other posts like this are submitted.
So there is a schedule. But the noise from everyone ignoring it and posting their own copy masks it, which is exactly why I dislike these rando copies of the question.
My comment about the schedule is based only on david927's posting schedule. I don't see the schedule.. they look like random dates during the month. If you see a pattern there, feel free to spell it out for me.
I also couldn't find any discussion with dang. link?
