In HCL Notes you have the possibility to import holidays from the Domino Directory where the holidays for each country can be centrally managed. This is a great idea !!
But I receive multiple requests from customers if it´s possible to import holidays from ICS files directly into your HCL Notes Calendar.
If you think that it would be great to have this option feel free to vote for this idea: https://domino-ideas.hcltechsw.com/ideas/NTS-I-1408
Right now I received a helpful hint from Oliver Busse that you can import ICS files not within an action but with the “normal” import function of HCL Notes ( File / Import ) and switch over to Calendar File (.ics ):
