Calendars

Connect Google Calendar, Outlook and Apple Calendar so your events sit beside your time blocks, and change them without leaving Chunk.

Connect a calendar

Chunk shows your calendars' events on its timeline, so you plan your tasks around them. Connect any number of Google and Outlook accounts, plus Apple Calendar.

Google or Outlook

  1. Open Settings with ⌘, and choose Calendars.
  2. Click + under the accounts, then Add Google account or Add Outlook account.
  3. Sign in to that account in your browser and allow access.
  4. When the page says Signed in, go back to Chunk.
  5. Tick any shared calendars you want. Your own are ticked already.

Apple Calendar

  1. In Settings → Calendars, select On My Mac.
  2. Click Enable Access, then allow it when macOS asks.
  3. Tick the calendars you want. You'll see every calendar your Mac's Calendar app shows, from any account.

If you said no to macOS, turn Chunk on in System Settings → Privacy & Security → Calendars, then click Recheck.

Choose what shows

  1. Select an account in Settings → Calendars.
  2. Tick the calendars you want under Calendars. Only ticked ones sync.
  3. Turn off Show in day view to keep the account syncing without showing its events.

To hide a calendar for a while, use the Calendars menu above the calendar. Its events keep syncing.

Change events from Chunk

Click an event to open it, with a Join link for its video call and Open in calendar.

  1. For a Google or Outlook account, turn on Allow editing in Settings → Calendars, then sign in again with the same account. Apple Calendar needs no switch.
  2. Drag an event to move it, or drag its edge to change its length.
  3. Click Edit calendar details to change its location or link, add a video call, or change the guests of an event you organised, except in Apple Calendar.
  4. In the same place, choose Show as busy, Show as free or Show as tentative. Google has no tentative.

When you change a repeating event, choose This event, This and following events or All events.

With Confirm edits on, Chunk asks before you drag, delete or convert an event. Changes in its popover save straight away.

Turn an event into a Chunk block

An event just for you, like focus time, can become a Chunk block you tick off and plan with.

  1. Click the event to open it.
  2. Click Convert to Chunk, the icon beside the bin at the bottom right.
  3. If it repeats, choose which events to convert.

The event leaves your calendar and a block takes its place. In a series, past events you include are removed, not copied.

Converting needs Allow editing for a Google or Outlook account. It doesn't work on events with guests, a video call, a location, a link or attachments.

Set calendar behaviour

Three settings under Calendar behaviour in Settings → Calendars apply to every account:

  1. Open locations in chooses Apple Maps or Google Maps for an event's location.
  2. Confirm edits asks before you drag, delete or convert an event.
  3. Calendar events trigger timer counts events down like your blocks.

Outlook categories

  1. To colour events by category, select the Outlook account and click Connect beside Category colours.
  2. To change an event's categories, open its Edit calendar details. Click + to add one, or right-click one to change its colour.

Categories show only in your own mailbox. A change applies across all of it.

FAQ

Why can't I connect my work Outlook account?

If Chunk says your organisation doesn't let it connect, ask your IT admin to approve Chunk, or connect a personal Outlook account.

Why can't I change a meeting I was invited to?

Only the organiser can, so its popover shows a lock. Read-only calendars, like holidays, work the same way.

An account has an amber dot. What does it mean?

Its sign-in has lapsed, so it has stopped syncing. Select it in Settings → Calendars and click Reconnect.

What's the difference between Allow editing, Confirm edits and the Claude switch?

They're three separate permissions. Allow editing lets Chunk change a Google or Outlook account's events. Confirm edits makes it ask before you drag, delete or convert an event. Let Claude edit calendars and reminders, in Settings → Claude, lets Claude create, change and delete events and reminders without asking.
