Calendar Open. I want that windows 10 calendar opens automatically at windows startup, in other words i want that the calendar fills the screen when i start my pc, but i couldn´t find a method. Open your calendar app without an internet connection and you’ll still be able to flick through your events and your days.
On the left, next to other calendars, click add other calendars create new calendar. Open your windows calendar and export your data to an.ics file (most calendar apps allow this in the settings or tools menu).
