copy data from start to end range

hi,

can anyone help me how to create a macro which will copy range of data based on a criteria? I have a worksheet which contains dates on column C rows C30:C64, dates would start from march 29 to may 2. how can I copy the range of data from April 1 to April 30? the criteria which will be copied will always be the start of the of the month up to the end of the month...meaning if the dates placed is like April 26 to June 6, it would automatically extract the range for May 1 to May 31 and place this on another sheet.

regards,

stoey
