Paid or unpaid holiday?

Halo Leute!
Im employed on a contract for three months in a restaurant. What I dont understand is my entitlement to paid vacation, i can't find clear enough answer for my specific situation. My question is: should I still receive 2 days of paid vacation per month of work if I work for less than 6 months? Some scources say yes  ,some say no.

“The full vacation entitlement starts after an employee has been on the job for six months. If an employee is terminated before these six months have passed or within the first half of a calendar year, the employee will only be entitled to 1/12 of the annual vacation entitlement for each month of the employment relationship. In the event of termination after the first six months and within the second half of the calendar year, an employee will be entitled to the full annual vacation.”
