I have the need to do high level planning at a month timeline. Have the excel 2007 purchased and am looking through examples. Gant by day is too granular a timeline of days, Gant Advanced is just a numbering timeline of week numbers. I understand that dates are just a number. Is there a way with Start date, end date to timeline months across a timeline? If you start at a day of 1/01/2010 serial number(40179) and format a cell to just month format it sort of works??????
