Friday and other days are red

Am populating the calendar and schedule with new term details, except the weekend and Friday is redded out meaning i cant put any ttable into Friday - i imported the school calendar from apple calendar and there is also random redded out days. Any ideas?

Hello artik,
If they are in red it means they are marked as holidays, that is why you can't edit its.
If you'd like to remove those holidays:
Tap on Calendar(on the ruler) > Tap on holidays > Clear holidays

You will have to do the automatic copy next, to fill those empty days

Regards
