In a tree calendar leap year either

an E sacrifice may be cancelled resulting in an extra day 29 on the end of a tree-month or
a 1 sacrifice is cancelled resulting in an extra day 0 at the start of the tree-month.

May be a leap day could occur in the middle of a tree-month with day numbering halted on the leap day.
