With the variable planner-day-page-template, you can define how
you want any newly created day planner pages to look.
You might want to include a section for your diary entries. For how to do this, see Diary.
You can add interactive Lisp buttons with the planner-lisp.el module. (see Interactive Lisp)
Your planner-day-page-template can also include ‘|<lisp>|’
tags.
For more complex day pages, you can set
planner-day-page-template to a function that will be called
from an empty day page buffer. The function should initialize the
contents of the day page.
