Good morning guys

I have a table with 3 colums

- First name
- date
- Hours off (number from 1 to 8 to account for vacation)

I would like to do a pivot table where the dates are grouped by months or
year and sum up the hours. for instance the following table

Joe 5/5/05 3
joe 12/5/05 8
Mike 1//1/06 8
Joe 1/10/06 8

Would give the following table
Joe Mike
May 05 3

December 05 8

January 06 8 8


Basically, regrouping the dates by month or year or by month and year in a
pivot table knowing that the source data is expressed in dates
