In this tutorial, we learn how to use a calendar for future projects in MS Project 2007. First, go to the "tools" menu, then down to organizer. Choose the calendar tab and then change what the calendars are available in. Choose ABC Limited, then click on "copy". Now, click on "close" and open up a new project. From here, go to "project" then "project information", and you will be able to change to the other calendar. Remember to change the default under the options so you have the correct times listed for your calendar, or your days will get messed up. When finished, you can use the calendars in any project you want!
