Because it reads from your device's native calendar, practically every calendar works — **iCloud, Google, Microsoft Outlook (Exchange), Yahoo, Proton, AOL, and any CalDAV calendar**. The first time, Sonto asks permission to use your calendars — choose **Allow Full Access**. Then click the **+** to add any calendar on your device. Calendars come from the accounts in your device's system settings — on Mac, **System Settings → Internet Accounts**; on iPhone, **Settings → Apps → Calendar → Accounts**. Any account there with calendars enabled shows up in Sonto automatically; there's no separate sign-in inside Sonto. ### Where events go One calendar is your **default** — new events and scheduled tasks go there. Change it in your calendar settings. An [area](/reference/projects-areas) can also have its own default calendar, so tasks you schedule from that area land on a specific calendar, shown in its own colour. ### Private events on Google Events Sonto adds to your calendar are marked **private**, so anyone with access sees only "Busy". For **Google** calendars, connect your Google account in Sonto settings (**Connect Google account**) to enable this — the standard Apple connection can't mark Google events private on its own. ## Calendar on the Day and Week screens On the day and week screens, Sonto shows your events right alongside your tasks, so your meetings and your planned work live in one view. Calendar events shown next to tasks on the day and week screens You can create and edit events, as well as accept or decline invitations, without leaving Sonto. You can also join video calls, either by opening the event and clicking the **Join Video Call** button, or, on Mac, by hovering over the event and pressing Cmd + J. An event open in Sonto with options to edit it and join a video call ## Tasks on your calendar You can drag tasks onto your calendar. This creates an event which is linked to your task — a *time block*. The event syncs to your calendar, so others with access to your calendar can also see it. The event is marked **private**, so they only see "Busy", rather than the full name and notes for your task. A task dragged onto the calendar, shown as a linked time block You can also create a time block by typing. Name a task `Review deck tomorrow 3pm 1h` and Sonto blocks the time for you — see [Natural language input](/reference/natural-language-input). Sonto can also place a task for you automatically, finding an opening that respects your working hours and existing commitments — see [Auto-schedule](/reference/auto-schedule). ## Availability Calendars work on both **Mac** and **iPhone**. Joining a video call with Cmd + J is a Mac shortcut; on iPhone, open the event and tap **Join Video Call**. ## Related A visual walkthrough of connecting calendars and blocking time.
