You could look up the Datenum() function in the help files for your dates.
Then you use the array based IIF function.
Something like this to get you started:
******
y1 = DateNum() > 1000101 AND DateNum() < 1010101;
y2 = DateNum() > 1010101 AND DateNum() < 1020101;
y3 = DateNum() > 1020101 AND DateNum() < 1030101;
period1 =IIf(y1,1, IIf(y2, 5, IIf(y3,2, Null)));
period2 = IIf(y1,2, IIf(y2, 10, IIf(y3,4,Null)));
Filter = DateNum() > 1000101;
AddColumn( DateNum(),"datenum");
AddColumn(period1, " p1");
AddColumn(period2," p2");
*******
Run the exploration to help you see if the results are as you expected.
