I would like to create a spreadsheet where I can I can exclude weekdays. I
want to only show weekends for this year, 2009
To obtain the first weekend day of "this" year, you can use this formula:
=MIN(DATE(YEAR(TODAY()),1,1)+7-WEEKDAY(DATE(YEAR(TODAY()),1,1)),
DATE(YEAR(TODAY()),1,1)+7-WEEKDAY(DATE(YEAR(TODAY()),1,1)+6))
If that formula is in D1, then
D2: =IF(WEEKDAY(D1)=7,D1+1,D1+6)
and fill down will return only the weekend (Sat/Sun) days.
If you want to "fix" the year, replace YEAR(TODAY()) in the above formula with
whatever year you want to start at.
