Hi, that is a big ask.

While I think it would be a nice feature, there are many considerations to make. Off the top of my head: would this be "per schedule" or "per node". Would it simply "not trigger" or "trigger with a flag"? How would updates be installed (i think it would require user to do an NPM update to get latest dates)

TBH, I think a separate node would be a better fit. Because users not using cron-plus (or for other situations not invliving cron/timed events) would be able to make use of it. This is the "better" design pattern where nodes are atomic (i.e. a good node typically does one thing and does it well!)

And note: you can do this yourself without waiting for someone to develop a specific node by simply importing date-holidays into a function node and testing the date yourself and permit the msg to continue or not.

Here is an example:
