Cal as a calendar implementation

I am trying to implement a calendar-like Cal application in my application.

Im using a synchronized scroll technique .

I want to know which of the best calendar libraries exists, since there are quite a few of them. briefly indicated the android-time square and caldroid ,

Can anyone suggest what is better to work with when you need to use it just as a view in a fragment or activity for easy scrolling synchronization?

Any other recommendations regarding the implementation of the calender are also welcome.

Thank.
