Calculate period of time taking into consideration the holidays and vacations

[Mohamed Eltaweel]

Hi,

In our workflows we have conditions based on calculated the period of time, for example if uat sent for approval for less than 10 working days keep the transition "Manual Sign Off" hidden. To calculate the period of time we usually hard code the holidays and weekend days (in the post function script) to get the correct period.

Is there any addon API's or Addon that I can use to simplify the calculation of the period of time based on predefined vacations, holidays, weekends on that Addon

Thanks
