I need use calendar in my app.

How i can make my calendar ?

In the Forge there are several calendar components.  Just search for 'calendar'.  (How come no one looks there first?)

Hope this helps,
i look in Forge calendar, but I dont know which component to use in my calendar.

recommends some component ?
No one can possibly answer that without knowing what your requirements are.  Provide a list of all the functionality your calendar must have and someone can probably help.  (Note - I've only played with a few calendar components so I'm hoping after you post your list someone else with more experience can help.)
