CLUSTER CALENDAR-COMMAND-LINE · 13 ENTRIES · EARLIEST ENTRY 2021-08-25

Command-line calendar and scheduling tools

This cluster comprises 16 products focused on calendar, scheduling, and date utilities, with many delivered as terminal or command-line interfaces, and a few offering web or voice-driven workflows. The dated history before the index start is thin, with only 10 entries spread across 2009-2026, and the largest monthly count is 2 in April 2026, so no clear growth pattern can be read from the available dates. Traction leaders (claude-agenda, cal_nongli, tock-rs-bin) all show zero stars, indicating minimal demonstrated traction.

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.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 13 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
