You can probably compress it a little. If you are matching a single character, then you don't need []:
[0] => 0
[:] => :
[0][1][0-2][\.]? => 01[0-2]\.?
.? I think needs to be quoted where you mean ".": . => \.?
Also, you can often use meta characters to save some finger work:
[0-9] => \d
[0-9]{4} => \d{4}
Also, some of the expressions don't need to be bracketed:
([0-9]{4}) => \d{4}
You only need the brackets if you want the parser to be able to treat it as a unit in larger ops.
Just some ideas. Nice work though!

One approach I have used with varying levels of utility is to treat the regex pattern like an algebraic expression. Factor out common terms and assign them to variables. Use replication counts, etc. This can simplify the final result and make it more maintainable.
Your pattern can be simplified a bit and made more readable somewhat by this. I found other strings like valid IP addresses can be greatly simplified this way.
Maybe this is useful to you!?

Has any looked at the MSDN pricing lately?
I do some MS Office (excel) integration for my customers so it requires that I get their version of MS Office (all the versions; 97 to 2013) to program against. To have access to Office I need to upgrade from the MSDN Pro to MSDN Premium... which costs $5000 more!
Can anyone explain to me how they can justify charging developers $5000 to integrate with their products? I'm not writing the president's speeches using these installs. I'm writing software so my customers will continue to use MS products and purchase licenses.
 I don't understand. What am I missing... besides the money to do it?

Nope, you didn't miss anything, it's the money.
It was broke, so I fixed it.

You've missed the point. Developers are MS life blood. If I'm buying a MSDN subscription then I'm a pretty serious developer. As a developer I keep my customers coming back for more when I meet their requirements and if I do that using MS technology then the customers buy more MS licenses.
Good business would be to let developers increase the MS bottom line by having them using more MS products in their solutions. Pricing their products out of a developer's solutions does not make any business sense.

You are making a couple of faulty assumptions: that MS care about developers, and the MS care about end users. They don't: they care about money. And the large companies they expect to sell the top-end product to will just pay up and move on, because it isn't the people signing the purchase order's money. While there are people who will pay it, they will continue to gouge charge.
Have to considered buying second hand copies of office on FleaBay to complete your collection that way, probably cost less than $500 for the lot...

Not true. Developers are the lifeblood of MSFT and we create the ecosystem from which they generate $billions of profit. Unfortunately, they do not understand the developer community. If they did, they would have free MSDN licenses for individual developers and charge for corporate licenses for those who develop commercial products. Developers like me generate huge revenues and profits for MSFT through SQL Server, Office, Azure, etc. licenses yet we have to pay dearly for the privilege (Visual Studio license fees, MSDN subscription, TFS, training fees and alike). It is just sad.

I agree with your conclusions but I don't agree that they don't care.
MS is made up of a bunch of developers and we're developers. I think that's just a brash and over-extended generalization. Unless you're saying that you don't care about the work you do and you suspect that all developers are the same way. Just like the company I work for, they are priced at "what the market will bare".
However, I do agree that its because we generally aren't the one filling the PO. Because we are one step removed they tend to get away with over-inflating their value. I'm just saying that it doesn't make business or logical sense that they'd price it with this much excess.
Yes, Fleabay is likely my next step. Got a copy of MS Office 97 for sale?

Just a realist when it comes to MS: I got fed up with Beta testing on DOS because they never listened to feedback even then.

Thank you for that generous offer, but I will reluctantly have to decline.

Teeth?
We used to dream of having teeth. They gave a pound of Tofu every month, and that was between seven of us! We had to suck it off the boss's doormats before letting out the Tartary Apes he used as Code Monkeys. And when they made mistakes, he'd beat us to death with Billy Gates' spectacle case.

Right.
It wa' Tartary Apes because th' boss were as thick as sh*t. 
If we tried to correct him, it were t' workhouse! At Facebook!
Young Tim Lee brought in his encyclopedia and boss made him eat it!
Afterwards he could only talk in 'Markup', which 'boss patented and turned to 'nternet.
And you tell youngsters today?
