Selecting two different periods for variable / calibration data

lets say I have a range of data between 1st Jan 2004 and 31st Dec 2007
Currently the script I am using uses the following code to select the calibration period:
A = find(T==datenum([2004 1 1 0 0 0])):find(T==datenum([2005 12 31 00 00 0]));
This uses data between 1/1/2004 and 31/12/2005 (or 12/31/2005 in American speak).
However, I wish to add an addition time period into this, so that A = 1/1/2004 to 31/12/2005 and at the same time includes 1/1/2006 to 6/6/2006
Matlab is certainly not a strong point of mine as you may have guessed - however I'm in urgeant need for my masters thesis so help is greatly appreciated!!
Many thanks,
P

There are better ways to do this, but the way that needs the less thought and the way you would understand the fastest would be:
A1 = find(T==datenum([2004 1 1 0 0 0])):find(T==datenum([2005 12 31 00 00 0]));
A2 = find(T==datenum([2006 1 1 0 0 0])):find(T==datenum([2006 6 6 00 00 0]));
A=[A1 A2];
Of course A here is just a list of indices, so you will need to do something like Data=T(A,:) to get the actual data.
