If you need to make a timeline for any project (they are a good way to visualise the amount of work that you need to do and to help you with organising your time) then you may want to check out timetoast.
Timetoast is a free to use (you do have to sign up) website that allows you to create a flash based timeline. Your generated timeline can then be shared with others and even embedded in your own webpage. You can also embed url links into your timeline.
Its pretty easy to use; I knocked up the timeline below in a matter of minutes.
