android calendar

Good afternoon. I try to download a calendar for my android phone, but without having to connect my phone to the internet to use the calendar. Indeed, my mobile plan does not include internet connections. Does anybody know how?
to clarify, I need to get a calendar of events and to be able to view, edit and be notified when the appointment is near.
thank you in advance for the answer

thank you again
