Extract from table all row between date

Hi,

I need to extract from a table a rows from:

3 to 6 months
over 12 months

I have done the queries but did not work:

1)SELECT data_pick FROM table WHERE data <=NOW()-INTERVAL 3 month AND 6 month;
2)SELECT data_pick FROM table WHERE data <=NOW() > 12 month;

Thanks in advance.
