Islamic date is one day behind in Apple Watch
Islamic Date (Hijra date) is one day behind on Apple watch. Already done following steps in iPhone:
Go to Settings > calendar > alternate calendar make it off .
then go to General > language & region > region choose “ Saudi Arabia “ after that go again to calendar alternate calendar choose Islamic calendar.
Now you can go back and change the region to what it was.
It does correct the islamic date on iPhone but Apple watch itself still one day behind. There is no setting for calendar in Apple watch.
I have also power cycled the watch.
