The function the_date(), when called in the Loop, prints the date in
successive posts only when the current day differs from the previous.
The idea is that you might want to print the day only when it's
different.

is_new_day() provides a test for the same idea, but more generally
(not just for the date).

But I would recommend against using is_new_day(), as it makes big
assumptions about global variables and the nature of Loop objects,
assumptions that are less likely to be true as more developers use
custom post types and multiple Loops.
