Say there is an automation setup in node-red routinely Monday-Friday. Now Friday is a public holiday so kids no need to go school, I’d like to disable this automation temporary just for this Friday. I can remember to disable at Thursday night and re-enable it Friday night. What is the simplest/best way to do this?
You could use the node ‘Bigtimer’ it’s an extremely flexible scheduling node. Go to manage pallet in NR and search & install from there.
this Friday is a temporary, next time could be Monday. I don’t think bigtimer will help in this case?
You can put the exceptions in advance in a google calendar. Put this integration in HA.
Then based on what is read from the calendar you can act on your automation.
This is what I am doing to manage exceptions in my heating schedule.

Hello, I have just read your question. I am currently working on another topic to try something out. I installed this extension in NodeRED …
The URL of an “ical calendar” can be included here. If there is a suitable calendar online for you, it might solve your problem.
Maybe you can integrate this 
to HA and start an stop the automation in NodeRED…

I’ll check out the ical integration. Thanks all for the idea!
Second vote for the Workday sensor. I use it in a lot of my NR flows to test if it’s a work day and turn on/off automations based upon it. Dead simple to setup and requires next to no configuration aside from the add_holidays list.
I briefly checked out ical and it should be ideal for my case. I can quickly insert an entry in calendar for the purpose.
Workday sensor works too, but I think need to update the configuration file(any quick way to edit on the phone?), which probably not as convenient as just insert a calendar entry. say I’m already on the bed and my phone is besides me 
Very well. Have fun with Home Assistant … 
if on android you can use the app QuickEdit and login through sftp (ssh)
