Today Calendar
Since our calendar serves mainly as an interface for Time Blocking, be sure to first learn and understand that feature in its dedicated article 👈
You can use our built-in Today Calendar to time-block and schedule your tasks and habits, and plan them into your day between meetings, appointments, and other events.
Connect your Google, Outlook, Proton, or any other calendar to see it in Lunatask – you can even connect Facebook to see your Facebook events there as well 🌟
To open the calendar in Lunatask, press the calendar icon in the main menu at the top. Alternatively, you can toggle whether the calendar is open by pressing CMD+S (on Mac) or Ctrl+S (on other platforms).

When the sidebar is resized wide enough, tomorrow appears – allowing you to plan your next day hour by hour (available on desktop).
Our Today Calendar isn’t intended to replace full-featured apps like Apple or Google Calendar.
Calendar integrations
⚡️ This feature is available on Premium plan
To see your calendar meetings and events right next to your tasks inside our desktop app, connect and authorize the integration in Settings → Connected apps.
Our calendar integrations are currently one-way only, with data flowing from external calendars into Lunatask. For more details and our plans around two-way sync, be sure to check updates on our Idea Portal.
While our desktop app connects directly to external calendar services through native custom-built integrations supporting all providers and protocols, the integration works differently on mobile.
Instead of implementing support for each provider and protocol, our mobile app reads your calendars and events using a native Calendar SDK on iOS or Android – in other words, Lunatask mirrors what you see in your system’s calendar app.
Since the integration with Proton Calendar (or any other calendar service) is handled outside our app – and as we use iOS ourselves – our knowledge of how to connect or subscribe to Proton Calendar on various Android devices is somewhat limited.
That said, based on past conversations with some of you, we understand there may be some privacy concerns. We don’t fully know the nature of those concerns – or whether it’s just one or there could be many, depending on your specific device or setup – but we can share a solution that one of you shared with us:
From how we understood the message – although we haven’t yet been able to try and verify it ourselves – if someone uses Fossify Calendar (an open-source/FOSS app) and connects their Proton calendar in it, Android’s Calendar SDK can then read events from Fossify Calendar and, as a consequence, they show up in our mobile app too.
Supported providers
All calendar providers and protocols are supported in our desktop app:
- Outlook
- iCloud
- Proton
- FastMail
- Hey
- Facebook Events
- Any other using an iCal/ics feed
- Any other using CalDAV protocol
On desktop, updates from external calendars sync to Lunatask in real time for Google and Outlook, and every 5 minutes for other calendar integrations.
On mobile, updates are synced every two minutes, or you can sync them manually using pull-to-refresh available across the app.
Alternatively, you can sync manually using CMD+R (on Mac) and Ctrl+R (on Windows and Linux), “Sync with cloud” menu item (on Mac), or a button in Settings → Diagnostics (on all platforms).
Having trouble setting up the integration? Feel free to reach out – we’re here to help. If you’re using Outlook / Office 365, please refer to our article on authorizing Outlook integration.
Joining video conference calls
⚡️ This feature is available on Premium plan
Lunatask automatically detects video conference and meeting links in events and shows a button for one-click jumping into the call – no setup required.

Supported video conferencing apps
- Zoom
- Google Meet
- Microsoft Teams
- Technical University of Munich (BBB TUM)
If you don’t see the button on your calendar events, send us a message and tell us which video conference tool you use – we’ll happily add support for it.
Creating notes for calendar events
⚡️ This feature is available on Premium plan
This feature hasn’t yet been ported to our mobile app – but it’s coming soon.
When everything lives under one roof, we can seamlessly connect things easily – like calendar events with notes. Hover over any meeting or event to reveal the option to create a connected note – this is great and not just for meeting notes.
Clicking the button opens a popup where you’ll be prompted to enter or select:
- Note’s name – by default, it’ll be prefilled with “Note for [event-name] from [current-date]”
- A specific notebook where to place the note (optional)
- Any note template you would like to use (optional, e.g. “Team Retrospective”)

The screenshot comes from an earlier version of Lunatask – while the design has changed, the functionality remains the same.
After clicking “Create note”, you’ll be taken to the newly created note, prefilled from the selected template (or left empty).

All that’s left now is to share the note with your teammates 🌟
Since the note is now linked to the event, clicking the button again will take you directly back to it.
FAQ
Is weekly/monthly calendar coming?
While continuously building, improving, and caring for what is essentially 6-7 apps in one, we’re still a small team of two – so we currently don’t have the capacity to take on the “calendar” use case just yet.
That said, you can still vote for this feature, share your ideas, use cases, and watch for updates on our Idea Portal 👈
How can I change colors of individual calendars?
Colors are pulled from your provider, such as Google Calendar. If you change the color there, it will update in Lunatask too – although we apply some processing, so it may not be an exact match.
Proton and iCal feeds don’t provide color, so their events appear in our default blue. We plan to add an option to manually pick a color for these – keep an eye on the current status of this feature on our Idea Portal 👈
Can I see different calendars in different lists? I don’t want to see my work calendar when looking at my personal tasks
This would bring more problems than it would solve, unfortunately. Your daily schedule is your daily schedule – regardless of what list you’re looking at right now.
Such a feature could easily lead to situations where you miss a work meeting because you don’t see it, or time-block a personal task for the same time you already time-blocked a work task without realizing it.
