If 3/11 was indeed a sign pointing to an upcoming event (s)...it is interesting to note the number of days to Passover, Feast of Trumpets, Atonement and Tabernacles.
It will be 38 days to Passover from 3/11
201 to Rosh Hashanah, the Feast of Trumpets
211 to Atonement
216 to Tabernacles.
Total = 666

Lets look at the gematria:

Passover..38
http://biblewheel.com/gr/gr_38.asp  (His Glory, His HEART (remember the Law written on the TWIN tablets of flesh)

Feast of Trumpets
201 or 21
http://biblewheel.com/gr/gr_21.asp (etc)  s

Atonement
211:  The Mighty, Fearful Word of God (etc)
http://biblewheel.com/gr/gr_211.asp  (I also this applies to 2011)

The Feast of Tabernacles
216: The Holy of Holies, The Lord will judge His People, Leprosy (etc)

It is interesting to note re: 216..that it is also related to the MOON. (remember the MOON has the Sea of Tranquility (SHILOH) as the earth has the Pacific (SHILOH) Ocean.  The moon's diameter is 2160 miles in diameter and is a symbol of the Bride who has "Leprosy" (symbol of mortality/sin) and must be purified for the "Holy of Holies".
 This is why, I believe, the Japanese "sun" also resembles a blood red moon. (and why the Sea of Tranquility faces earth, holding a " mirror" of the Pacific (Shiloh). 
The 216 days to Tabernacles, from the quake/tsunami on 311 even carries the code or sign within it's timing.  216 days is 5184 hours or 311040 seconds.
Again.....adding the day numbers from 311 to the Feasts...we have 666:
