Working hour setup

Hi,

We have requirement of configuring some calendar days as specialdays (holiday) for the process. And this needs to be configured every year.
What I understood from the working day functionality; if we change special days every year, K2 process need to be redeploye every time.

Is there anyway by which I can reconfigure specialdays without redeploying the K2 process?

Thanks & Regards,
