Merkuro Calendar
What Merkuro Calendar is
Merkuro Calendar is a free, open-source application for organizing events and tasks on Linux and Windows. It connects to local calendars and online calendars such as Nextcloud, Google Calendar, Outlook, and CalDAV. Events can be viewed in month, week, or schedule layouts: the month view covers a full month, the week view shows an hour-by-hour plan, and the schedule view lists upcoming events. A separate task area arranges tasks and subtasks in a tree, with customizable filtering. KDE says Merkuro is intended for desktop, mobile, and intermediate device sizes. Linux installation is available through Discover, other AppStream stores, or a distribution package manager. The Windows download is a nightly installer intended for testing. The application is licensed under GPL-3.0-or-later. KDE’s privacy policy says information is generally transferred only after explicit user action, while telemetry is opt-in and disabled by default where present. KDE provides forum, Matrix chat, source, bug-reporting, and translation links.
