Believe it or not, it wasn't the latest national holiday that made me look for an alternative to the Samsung or Google calendar. I think it was the Google calendar that had one day a month denoted as some Wokester fake holiday of one type or another. You know, "National LGQBT#6&;$ Day" or some such thing.
The best thing you can say about Woke holidays is that they are no more propagandist than traditional holidays like the Fourth, Veteran's Day, and Memorial Day. These are the fake holidays when we are supposed to worship the Pentagon.
Before we had Pentagon-worship holidays, there were religious holidays, be they pagan, half-Christian, or medieval. And they were all based on bullshit, superstition, and lies. So in a sense, Woke holidays are completely traditional.
I found "Simple Calendar" on the Google Play Store. The "Settings" allow you to simply not show any holidays. Thank you, Simple Calendar. I want a calendar to remind me to pay a bill, and that is all. And maybe the solstices and equinoxes and Mother's Day.
