Calendar

Calendar in the sidebar shows, on one month, everything with a date that you're allowed to see. The dashboard's Upcoming card shows the next two weeks of it: open deadlines, your meetings that haven't happened yet, and upcoming bookings.

Who can do this: everyone. What's on it depends on your role and on which projects you can see (see What's on it).

What's on it

Each kind of item has its own icon and colour, and links to where you can act on it.

Item	Shows	Who sees it
Meetings	Your meetings from the calendars you connected under Profile → Calendars, at their time: the last two weeks and the next 30 days. Ones still to come are marked Upcoming; ones that have ended are To sort, Logged or Ignored as in Time → Meetings.	Only you. Nobody sees anyone else's meetings.
Bookings	Meetings booked through Cal.com or Calendly, at their time, with who booked (a draft client is labelled) and Cancelled or No-show when they are. A booking that's also in your own calendar shows once, as your meeting.	Owners and admins: every booking. Others: the ones they host.
Tasks	Due dates of your tasks, or everyone's (Everyone's tasks). Overdue ones are red; done ones are struck through.	Anyone, for projects they can see.
Milestones & deliverables	Due dates of milestones and deliverables.	Anyone, for projects they can see.
Project dates	A project's start and end dates (set with Edit on the project).	Anyone, for projects they can see.
Invoices due	Due dates of sent, unpaid invoices.	Owners and admins.
Scheduled sends	Drafts scheduled to send, at their time. One that failed is red.	Owners and admins.
Recurring invoices	The next run of each active retainer.	Owners and admins.
Billing cycles	When each client's billing cycle next closes and invoices its unbilled work.	Owners and admins.
Estimate expiries	The last day a draft or sent estimate can be accepted.	Owners and admins.

Nothing from a confidential project you aren't on appears, and archived projects are left out.

How to use it

1. Open Calendar

   Click Calendar in the sidebar. It opens on this month, with today circled.

2. Move between months

   Use the arrows next to the month name; Today brings you back. The month is in the address (?month=2026-11), so you can bookmark or share a view.

3. Switch views

   Month is a grid; a day with more than four items shows +N more, which opens that day in Agenda. Agenda lists every day of the month that has something on it, with the client and project of each item. On a phone, the month shows only days with something on them.

4. Filter

   Pick a client or a project, and My tasks or Everyone's tasks. Click the chips (Meetings, Tasks, …) to hide or show each kind.

Meeting times are shown in your browser's time zone (the page says which, at the bottom). Due dates are whole days and are the same everywhere.

Due dates on tasks

Give a task a Due date when you add it, or with the pencil (Edit task) later. It shows on the task's row and sheet: red once it's past, amber the day before and on the day. See Tasks.

Deadline reminders

The daily job (see Self-hosting → Scheduled jobs) sends these once per due date. Changing the due date re-arms them.

Reminder	Who gets it
A task is due tomorrow	The task's assignee, in the app and by email to their own address.
A task or milestone is overdue, for a task	The task's assignee, in the app and by email to them.
A task or milestone is overdue, for a milestone or deliverable	Owners, admins and the people on the project, in the app; Slack and the alert email list, per Settings → Alerts.

Done tasks, completed milestones, unassigned tasks and projects that are completed or archived don't get reminders. Owners and admins choose Slack and email for each under Settings → Alerts (see Alerts); the in-app notification is always sent. On a confidential project, Slack and email leave out the task, milestone and project names.

Subscribe in your calendar app

Get your deadlines in Google Calendar, Apple Calendar or Outlook with a private address only you have.

1. Create the address

   Go to Profile → Subscribe in your calendar app and click Create calendar address. Copy it: it's shown only once.

2. Add it to your calendar app

   • Google Calendar: Other calendars → + → From URL, paste it, then Add calendar.
   • Apple Calendar: File → New Calendar Subscription, paste it.
   • Outlook: Add calendar → Subscribe from web, paste it.

The feed has all-day events for your tasks' due dates, milestones and deliverables, and project start and end dates, plus (for owners and admins) invoice due dates, scheduled sends, recurring invoice runs, billing cycle closes and estimate expiries: from two months back to a year ahead, for the organization you had open when you created it. Done items end in (done). Each event links back to the app. Meetings are never in it; they're in your calendar already.

It's worked out from your access whenever it's read, so if you leave a project or the organization, its items drop out (within a few minutes). Only a hash of the address is stored.

Make a new address replaces it: the old one stops working at once. Turn off removes it. Do either if the address might have leaked: anyone with it can read your deadlines.

Check it worked

Your calendar app shows a calendar named Consultainer — your organization, and Profile says last read by a calendar app with a date. Opening the address in a browser shows (or downloads) a calendar file that starts with BEGIN:VCALENDAR.

Troubleshooting

Over the API and MCP

Tasks take a dueDate (YYYY-MM-DD) when created or updated, over the REST API and the MCP server (create_task, update_task; list_my_tasks lists the soonest due first). An invalid date gets a 422 (API) or an error (MCP). Owners and admins can schedule invoices with schedule_invoice_send.
