Question: Q: Change the U.S. holiday calendar back to U.S. holidays!!

It appears Apple's late February response to the outcry at the removal of religious holidays (which only represented Christian events) from the calendar was to put holidays for all major religions on the calendar. Subscribe to a calendar that only has what you want.

Why is there now Islamic and Hindu holiday's are my U.S. holiday calendar? What happened to Good Friday too? How can I removed the holiday's in which I do not support or participate in? These are even American holidays!!

The religious holidays added recently are just as American as Easter. Like Easter, Holi, for example, started in another country, very far from the U.S. Like Easter, Holi is celebrated by U.S. citizens.

The real American holidays don't appear to be on the new calendar. However, for your convenience, they're listed here:
