CLUSTER CALENDAR-DESKTOP-LINUX · 20 ENTRIES · EARLIEST ENTRY 2022-05-01

Desktop calendar apps

This cluster consists of desktop calendar applications, predominantly for Linux, that handle event viewing, syncing with services like Google and CalDAV, reminders, and specialized layouts such as Gantt or lunar phases. The dated history shows single entries scattered across 2016, 2018, 2021, 2022, 2023, and 2025, then a slightly higher frequency in 2026 with multiple entries in some months. Traction is uniformly low, with the leading members shadowdate, DankCalendar, and Kairos each showing 0 stars.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
