MS Project (2010, 2007, 2003 etc) all have one Standard Calendar (which is a global calendar for everyone) It is NOT a good idea to copy this and call it "My Company" calendar as then you have 2 global calendars ( I once trained a company that had 4 global calendars - yes they were confused. The resources are set up to make a copy of the Standard Calendar and you do not have to do anything. If you copy and create your own Standard Calendar "My Company" then you will have to change all the defaults - lots of work for you and zero advantage MS Project 2010/2007 training Toronto, Mississauga, Hamilton Ontario Bert Twomey MS Project Trainer
