The past few days when I start up my car there is a high pitch squeak/squealing sound (not continous either) but is 'coming more' often than 'going'! Almost sounds like it could use some WD-40, but I'm sure that isn't[ as simple. Could it be a timing belt? How or when do you know?
Thanks a bunch!

Change the belt and check belt tentioner while taking it off make sure its good and tight should only take 15 min or so look at routing picture to put new one on

If you do replace the belts, then be certain to change the tensioner and idler pulleys. I had the same issue and I just had to replace the pulley, not the belt.
