I have a project that will run 24 hours a day until it's finished,I can't get
the calendar to change to a 24 hour one. how can I change it for this
project?

Do the following:

1. Click Project - Project Information.
2. Click the Calendar pick list and select the 24 hours calendar and then
click the OK button.
3. Click Format - Timescale and then select the Non-Work Time tab.
4. Click the Calendar pick list and select the 24 hours calendar and then
click the OK button.
5. Click Tools - Options - Calendar.
6. Change the Hours Per Day value to 24h.
7. Change the Default Start Time value and the Default End Time value to
12:00 AM.
8. Change the Hours Per Week value to 168h.
9. Click the OK button.

If you have resources in the Resource Sheet view of your project, you should
also change their Base Calendar value to the 24 Hours calendar as well.
Hope this helps.

But think a moment before you do this. A proper work breakdown defines a
task as a physical activity done by a single resource resulting in a single
deliverable. If you use the 24-hour calendar as your Project calendar,
you're implying that once a task - let's say one that requires 100 man-hours
to complete - has started, the poor individual assigned to do that task
won't get a meal break, won't get a nap, won't see the family, etc for at
least 4 days, working without interruption until the task is done. People
just don't work like that. If you have activity that runs for 24
consecutive hours, different people are doing it during the day, in the
evening, and overnight. You don't cover that with a single 24-hour
calendar; you cover it with at least 3 single (typically 8-hour) shift
calendars - one for the people working day shift, another for the people
working swing, and the third for the people working graveyard. Pick the one
that decribes the work hours of most of the people working on the project
and make that the Project calendar, while assigning the base calendar that
describes each individual resource's shift as their controlling calendar in
the resource sheet.
