Last row in a column that contains a date.

[eduzs]

I need to retrieve the first and the last row in a column that contains date.
Is there any formula that can do that?
The column have mixed data (values, dates, text)
Thanks

Care to post 10 rows from the column in question along with the desired results? Note that dates are also numbers like 0.1, etc.
