Hello!

Just a question about the calendar . In the custom fields are present date value. When viewing the calendar in addition to the standard date and the present date, are added to the custom fields . How do I remove the date of standard and custom fields date from a calendar ? Need a search . The standard filter is not helping . Maybe there are alternative options for the calendar ? The task of such a calendar to display only the date of the custom fields , and then only those that are needed .
