What is the maximum number of days a worker can work without an off day?

Hello,

Appreciate it if anyone can give clarity on the below Article of UAE labor law, Article (19):

Overtime

5. A worker shall not be instructed to work for more than two consecutive weekend days, except for day workers.

As per the above point, if a company gives Sunday as a rest day, what is the maximum number of days a worker can work without an off day?

Since it says "weekend days", can he work 14 days or 20 days? That means workers can work till the 3rd weekend.

Please advise!
