Worth knowing
GNOME Calendar
- Linux only: it is distributed as a Flatpak on Flathub, and the project lists no Windows, macOS, Android, iOS or web version.
- Calendars are stored and synced through Evolution Data Server, the GNOME component the app is built on.
- Help comes from the community chat and the issue tracker; the project page lists no paid support.
- Sound-only alarms were removed in version 50, so every reminder now shows a notification.
Merkuro Calendar
- Stable releases are for Linux. The Windows builds on KDE's site are nightly installers that KDE labels unstable and intended for testing.
- It depends on Akonadi and KDE PIM packages; without kdepim-runtime, the project says the calendar component is heavily restricted.
- The Kontact Flatpak that includes Merkuro lacks some desktop integration, such as the calendar applet plugin, so KDE recommends a distribution package.
- Proton Calendar cannot be connected, and services with non-standard calendars or task lists, such as Todoist, are not supported.
Key features
GNOME Calendar
- Month, week and agenda views
- A month view that scrolls without end, a week timetable and a scheduling list. Since version 49 the sidebar can be hidden and the window adapts to narrow widths.
- Online and local calendars
- Calendars can be added from services such as Nextcloud, Google Calendar and CalDAV or WebDAV servers, and local calendars work without a connection. The project describes calendars and events as unlimited.
- ICS file import
- Opens .ics files and imports their events through an importer dialog that previews them with their time zones. Since version 47 a file can also be dragged onto the window.
- Time zones, recurrences and reminders
- The start and end of an event can each be given a time zone, recurring events can be created and edited, and reminders appear as desktop notifications.
- Weather and video-call links
- Weather forecast temperatures are shown in the Month view when there is room. Recognized videoconferencing links are labelled with the service name, and version 51 added support for Teams links.
- Keyboard navigation and screen readers
- Versions 49 to 51 added keyboard navigation between days and events in the Month view and made event widgets readable by assistive technologies such as screen readers.
Merkuro Calendar
- Month, week and schedule views
- The month view gives an overview of the whole month, the week view shows each day hour by hour, and the schedule view lists upcoming events in order.
- Tasks and subtasks
- A separate task view shows tasks and their subtasks as a tree, with filters that can be customized.
- Local and online calendars
- Supports CalDAV calendars such as Nextcloud, Google and Exchange calendars, iCal files and folders, and Kolab and Open-Xchange groupware servers.
- Sync through Akonadi
- KDE's Akonadi framework fetches, edits, creates and deletes events on remote services. The project recommends installing the kdepim-runtime package before starting the app.
- Plasma clock widget integration
- Events can appear in the calendar of Plasma's digital clock widget by enabling the PIM Events Plugin in the widget's settings and choosing which calendars to show.
- Desktop and mobile layouts
- The interface is designed for desktop, mobile and sizes in between, and the listing includes a mobile view. The project describes it as syncing across a Plasma desktop or phone.
