is there a way to add national festivity to the windows 10 calendar?

1.) Click More Calendars
2.) Select the Calendars you'd like to add
3.) The added Calendars will be shown under Holiday Calendars

You are welcome :)

Is this new? I can't remember seeing that before.

When I tried a month or so ago, I can only remember seeing Settings > Calendar Settings > Add Holidays (which was just a hyperlink to Office.com, with instructions that don't apply to outlook.com).

Anyway, thanks for the info.

Edit: Can confirm this is new (the part with being able to add multiple country calendars) as it's only present in the calendar app on one PC, not another that hasn't updated for a while. It seems it was introduced at the same time that 'Year View' at the top was introduced. Not on Windows 10 Mobile or Outlook.com yet.

Edit 2: Be warned though, just like everything coming out of Microsoft now-a-days, it's buggy. I added a second country calendar, but the entries later disappeared from the calendar for reasons unknown. So, I removed the calendar by unticking the country and re-added it again by re-ticking the country. Now there are two calendars for the same country with no way to delete the original one. Great. And because it's a built-in store app not just a win32 application, re-installing the calendar app is a PITA.
