Have a sheet with some 500 rows.

Each row has in column A a date (ranging from januari 1 to whtever end date
but lets say december 31).
In the remaining columns are values I need belonging to the dates
(laboratory results to be more accurate) .
I need a macro that deletes all rows with a date NOT in quarter 1.

Think its easy, but I cannot make one that quick..... :-)
Who...?

thx
H.
