The app source file

https://github.com/FossifyOrg/Calendar/blob/master/app/src/main/assets/netherlands.ics

should be a copy of the upstream version

https://github.com/PanderMusubi/dutch-holidays/blob/master/NederlandseFeestdagen.ics

Please add in the build process an automated check if this file needs to be updated with upstream.

Nice!

What do you use as upstream? For the Netherlands, please don't use the one offered by Thunderbird. They use the same upstream eventually, but can also lag behind as they don't check for updates automatically.

Additionally, Thunderbird has changed the way they generate holiday ICS files and caused also for missing holidays for the Netherlands. This is an ongoing issue, so sidestep them for NL for the holiday calendar.

I will answer, since I implemented it. We don't use Thunderbird's database, but https://github.com/commenthol/date-holidays. Here's explanation why: #152 (comment)

Thank you for the explanation. That is another source and I will contact them to make some improvements and additions.
