Launch the Calendar Wizard

Do not have a frame selected, or a curser active in a text frame, then double clicking on calendarWizard.js in the Scripts pallete.

You can also use "calendarWizard-classic.js" or the "gridCalendar.js" under legacy-launchers. That will bring up the classic interface which is faster, but less interactive.

Adjust the Settings

By default, the Text Layer is automatically selected, so it is not necessary to add it.

Commentary

The Text Layer contains a super-imposed table tied to unique cell and paragraph styles. One of the key values is to add/edit text without distrubing the content or layout of the date in the cell.
