#1 What checks are included in is_date()

is_date() contains in itself functions is_day(), is_month(), is_year() and etc.

This example demonstrates how not to do:

if( is_date() )
	echo "It's an archive by date";
elseif( is_day() )
	echo "It's an archive by day";
else
	echo "This is something else";

In this example, the is_day() condition will never be met. It needs to be checked before is_date().

#2 Basic usage 

if( is_date() )
	echo "It's an archive by date";
else
	echo "It's not an archive by date";
