CLUSTER DAYS-OFF-TIME · 6 ENTRIES · EARLIEST ENTRY 2025-06-05

Vacation and PTO planning tools

Cluster of seven products focused on vacation and paid-time-off planning: business-day and PTO calculators, an employee vacation scheduler that flags overlapping time off, and mobile or trip-oriented day-off trackers. Only 3 dated entries exist before the index start, so the cluster's dated history is too thin to read a shape from. On the activity signal provided, the listed leaders (crew-vacay-planner, global-business-day-planner, Vacation Buddy: Trip Planner) all sit at 0 stars, so no member stands out on 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 6 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
