Because of the complexity of this type of date flow, using a comparative year token in a monthly GridTemplate which uses the Backtrack_every_page structure, is not allowed to avoid producing meaningless results.

In any event, if you are using such a grid, you know exactly which DayValues belong to which month and you do not need to use comparative month tokens to compare the month of 2 different DayValues.
