There are many of us who spend untold hours researching and digging deep into the evidence provided by Q and other sources and in an attempt to attain greater understanding, make educated guesses as to the chronology of certain "happenings." In contrast, Q has never given a definite date-set, which makes sense if you think about it. If the DS were aware of the exact timeline, they could counteract and get ahead of the patriots fighting behind the scenes. The March timeline was a researched guess as to the when of the unraveling based on many members studies but not a timeline given by Q.
