The built-in holiday calendar on my iPhone 8 running iOS 12.4.1 is off by one day. For example, it shows New Year's Eve on December 30 and not on December 31.
So far I tried to :
- Enable automatic date & time in
Settings > General > Date & Time > Set Automatically = "On"
- Desable the time zone override in
Settings > Calendar> Time Zone Override = "Off"
- Reset the iPhone
- Switching off automatic date & time and entering my time zone then switching back to automatic
- Switching off Location Services and GPS in
Settings > Privacy > Location Services.
then switching back on
What could I do next ?
Note: My personal calendar doesn't have the issue nor my MBP's calendar ; but I added another location holiday and it have the same issue...
