like in subject i need to build event calendar showing all month days or specific range of days but displaying every day, even ones with no CMS item/ with no event. Best would be situation where clean calendar generetes itself and adding events as CMS items puts them into calendar. And it is highly demanded to be free or paid-once solution – not subscription.
You can choose day and see events on that day but days with no events are inactive.
Antother option is to display grid with all month days and events inside, like here: https://www.drupal.org/files/project-images/bigcal.JPG
Can anyone help?
