No, you are not. With the sole exception of certain retail employees in MA, RI and possibly CT, no non-exempt employee is legally entitled to holiday pay, ever, unless guaranteed by binding contract or policy.

If you are normally a part time employee, it doesn't matter if you are temporarily working full time; if part time employees don't get paid for holidays, they don't have to pay you for holidays either.
