When

When is a self-hosted group scheduling poll: when2meet’s availability grid, rebuilt API-first. Everyone paints the times they’re free, and the heatmap shows where the group overlaps.

What’s different

• Two kinds of yes. People can mark times as available or if needed. When ranks slots with “if needed” worth a third of a full yes, so a wall of reluctant maybes doesn’t outrank a real consensus.
• Time zones done right. Answers are stored as absolute instants, so someone in Berlin and someone in Los Angeles fill in the same row and mean the same moment, including across daylight-saving changes.
• A grid that works on a phone. Long-press to start painting, so the page still scrolls normally under your thumb.
• Agent-ready. The public page and the organizer dashboard are ordinary clients of the same API, and an MCP endpoint lets Claude create a poll, check who has answered, and report the best times.
