The Madrid bombing was exactly two and and half years after 9/11. 
The Bali bombing was 1 year, 1 month and 1 day after 9/11.
9/11 happens to be the US emergency phone number. 

My question is quite open, but answers need to include any of the
following or along the same line of thinking:

- Is there any pertinent religious aspect to these dates or timeframes?
- Is there any precedent for terrorists using non-obvious anniversaries?
- Had anyone predicted the date of the Madrid attack?
- Has anyone or can any researcher calculate a date for the next
attack - where the formula fits the three previous attacks as well?
- Do any of the lesser (in terms of bodycount, but each are obvuously
tragic) attacks fit into a pattern?

Comments obviously very welcome. Answer should make the average person
go "wow, I'm convinced".

Clarification of Question by robertskelton-ga on 13 Mar 2004 04:18 PST

Just found out that not only was Madrid 2.5 years after 9/11, it was
also 911 days. That's just creepy. For that to be by design, they
must've planned both dates from the very beginning. The same site also
provided this less interesting numerology-type data:

911 days after 9/11 
on 3/11 four trains instead of four planes 
13 (!) bombs (10 went off, 3 were diffused) 
3 / 9 / 11/ 13 pretty symbolic numbers there! 

The numerology linked to 9/11 

WTC Facts: 

The date of the attack: 9/11 - 9 + 1 + 1 = 11.
Each building had 110 stories.
After September 11th there are 111 days left to the end of the year.
September 11th is the 254th day of the year: 2 + 5 + 4 = 11.
119 is the area code for Iraq/Iran. 1 + 1 + 9 = 11, 911 - 119 are
opposites - enemies?
11 11 polarity.
Twin Towers - standing side by side, looks like the number 11.
The first plane to hit the towers was Flight 11.
State of New York - The 11th State added to the Union.
"New York City" has 11 letters.
"Afghanistan" - 11 letters.
"The Pentagon" - 11 letters.
"Ramzi Yousef" - 11 letters (convicted of orchestrating the attack on
the WTC in 1993).
Flight 11 - 92 on board - 9 + 2 = 11.
Flight 11 had 11 crew members onboard.
Flight 77 - 65 on board - 6 + 5 = 11.

Flight 11, 93, 175, 77 - If these numbers are broken down, 11 actually
remains the same in numerology, 93 becomes 12, 175 becomes 13 and 77
becomes 14. 11 - 12 - 13 - 14 Broken down again and you have
2 - 3 = 4 - 5. Add them all up and break them all down! 

11 + 93 + 175 + 77 = 356 = 14 = 5
11 + 12 + 13 + 14 = 50 = 5
2 + 3 + 4 + 5 = 14 = 5

Twin Towers =11 + Flight 11 + September, 11th = 33

Regarding the choice of the date 9/11, this may be of interest:

I am a muslim from Pakistan and I do not believe that their is any relation
of 9/11 to any event of muslim history.The resean is that we as muslim use
our islamic calander,which is based on moon and not on sun, for all of
our events in Islamic history.

I have also read link mentioned by pinkfreud-ga and I do not agree
with the defeat of ottoman empire on 9/11,1683.Kindly keep in mind
that the defeat was
of turks and in 9/11 involvement is of Arab and both nations have
historical clash even both are muslim nations.

I also wish to mention here that we, the muslim, do not believe that 9/11 was
menaged by alquaida or any other muslim organisation or any one from
muslim world can do such a big job.On this subject their are so many
question even in the western world which still have not been answered.

Dear Rob, 

First of all, I hope you are aware of the fact that Muslims use a
different callendar.

Izaj Ahmed have written "we, the muslim, do not believe that 9/11 was
menaged by alquaida or any other muslim organisation or any one from
muslim world can do such a big job." I actually know many Muslims who
do believe that "Al Qaida or any other Muslim organisation" have
committed those attacks. It is hard to speak on behalf of a
world-religion, that includes people who support these attacks as well
as people who are disgusted by these attacks, including American
Patriots who serve in the U.S. military forces. There are people of
all types and colours and it would be a mistake not to notice that
also Islam could produce such organisations.

Just to add to the creep factor...
   
On September 11, 2002, the winning New York State lottery numbers were
9-1-1. The state called it a "coincidence". What makes such a matter
even more weird is that last November 12, 2001, American Airlines
Flight #587 crashed in New York City. That day, the New Jersey State
lottery winning numbers were 5-8-7!  According to the Associated
Press, many people found these lottery results to be "chilling and
maybe suspicious, too."
   
Here's the story:
http://www.yorknewstimes.com/stories/091302/nat_0913020041.shtml

I get that March 11, 2004 is 912 days after September 11, 2001, not
911 days.  Remember 2004 is a leap year.  I can already picture the
rebuttal to this: "well, that means there are 911 days BETWEEN the two
dates!"  This is just an illustration of the kind of thinking which
is, in my opinion, the explanation for the 'coincidences' surrounding
numbers involved with 9/11. I am almost surprised that "Osama B.
Laden" is not listed as one of the names/words/phrases with 11
letters.  Doesn't the guy ever use a middle initial?  I think it is
likely that there is no significance to any of the numerology-type
things said about 9/11.  The thing is, if you're willing to play games
with things like the number of floors in buildings, airline flight
numbers, and dates when historical events occured, you could make ANY
circumstance seem 'suspicious' with a little creativity.  How likely
is it really, though, that the terrorists picked flights based on the
flight numbers, rather than on practical factors like when the flights
took off, and from where, and how many people were expected to be on
board?

You will not find a numerologist who will predict with confidence the
date of the next big terrorist attack.  But I will make the following
prediction confidently: when the next attack occurs, it will be found
to be 9 months and 11 days after something, or maybe 9 days and 11
hours, or it will happen in two places one of which has 9 letters in
its name, and the other 11, or in any case, there will be a
'coincidence' involving numbers.  Because there are so many possible
'coincidences' that some of them are bound to occur.

In the matter of the lottery coincidence, it's not really all that remarkable:

Just a minor point of clarification: The country code for iran 098 and
for iraq 0964.
There must be some simple explanations for the rest of the facts as well.

Skeptics who did the calculations came up with a 912-day difference
between the two events, leading the to conclusion that someone had
miscalculated or neglected to account for 2004's being a leap year.
Who's right depends upon how one describes the temporal relationship
between two dates.

Let's say April 11 is already a date of significance, and something
noteworthy occurs on April 14. How do we describe the relationship of
the latter day's occurrence to the earlier date? We could say that the
noteworthy event:

Happened on the fourth day
Took place three days later
Was separated from the earlier date by two days

The middle option is the most common way of expressing this type of
relationship between two dates, and the one that produces a 912-day
difference between the September 11 attacks and Madrid bombings. The
latter option, although less commonly invoked, does validate the claim
that there were 911 days between the two events. (To put it
symbolically, if event B occurs (n) days after event A, then (n-1)
days fall "between" the two events.)

In any case, there is no evidence that whoever was responsible for the
Madrid bombings deliberately planned them to take place on a
numerically significant date. (The only speculative motive expressed
so far for the choice of date was that the bombings might have been
timed to influence the Spanish national elections scheduled to place a
few days later.)
