Hi Todd,
Welcome back, I examined problem that you described, and this is what I came up with. WP Chrono is actually already supporting translation and multi-language. Having that in mind, if your web site has properly configured secondary language and properly translated days, then the plugin will print out days fine (if not, default is English).
For example, this is working WP Chrono on Deutsch web site: https://prntscr.com/fwl449
Notice that Monday is translated to Montag.
Plugin actually uses WordPress function which does this by default, so WP Chrono is small plugin, and is not affecting translations, it simply prints out what the rest of the WordPress mechanism provides.
Having that in mind, I see two ways you can handle your issue:
1) Examine if translations for days are working correctly (this issue is not related to WP Chrono plugin)
2) Use some different format, which will print only numbers without name of the day.
For example, if you use this format:
[wpch-currentdate format=”l?Y-m-d G:i:s”] , l – stands for full name of the day
you will get name of the days.
If you remove l:
[wpch-currentdate format=”Y-m-d G:i:s”] – name of the day won’t be included
I hope this will help you in resolving your issue.
All best,
