Find Meeting Windows That Reach a Chosen Attendance Count

A group can have plenty of available hours but no interval with enough people together. Enter anonymous availability codes and a minimum count to see exactly which same-day segments meet it.

1 · anonymous member code | available from HH:MM | available until HH:MM

FIRST-LOAD

HYPOTHESIS / PROTOTYPE — checkout unavailable. Calculation is local. A draft is saved automatically in this browser profile when storage is available; Reset to sample clears it. Optional Pro history stores only five summaries and has its own deletion control. State links encode your inputs and can remain in browser history, clipboard or recipients’ records; share only non-sensitive rows. Optional external AI formatting leaves this device. The required site analytics beacon reports page activity; shared URLs contain encoded inputs. Do not treat an encoded URL as private. The calculator has no input-collection endpoint.

Data note: The attendance-window rail processes anonymous member code | available from HH:MM | available until HH:MM locally. Starter/sample selection and Run compute in this tab; no input is sent by the calculator. A local draft may be saved; explicit state-link sharing or optional external AI formatting can disclose inputs. Use non-sensitive labels.

Perspective: Before: total available hours hid simultaneous headcount. After: each boundary segment shows who is counted anonymously, without claiming a legal quorum.

2 · Read the attendance-window rail

Availability arithmetic only, not legal, governance or quorum advice. It does not verify membership eligibility, meeting notice, remote participation rules or a valid vote. Confirm the rule and proposed slot with the chair or qualified governance adviser; retain anonymous codes and obtain attendance confirmation separately.

Optional filing controls are a local prototype.

Checkout is unavailable. The reading above is complete; print, CSV and five local summaries are optional enhancements, not hidden answers.

Before using the attendance-window rail

Use a count agreed by the organizer, not a threshold invented from a generic quorum rule. Membership classes, remote attendance, conflicts of interest and the type of decision can affect a real organization’s requirements. This instrument intentionally does not parse those rules. One anonymous member gets one interval for the same local day; split-day availability needs a separately confirmed model rather than duplicating a person and counting them twice. The displayed rail changes at every start or finish boundary so a short bottleneck cannot disappear into an average. Keep the source availability and the eventual invitation separate: the tool cannot send a calendar invite, hold a room or turn a stated window into a commitment. It helps the organizer ask a concrete scheduling question.

Optional AI formatting, never the calculation

Manual entry completes this attendance-window rail for free without signup. If available to you, the free AI Studio interface linked in the sources may format fictional or non-sensitive notes; external access may require an account. No API key or AI call is built into this tool. Free-tier content may be used to improve products. Review each cell and transcribe it to the labeled row schema; do not paste the JSON object into the row box.

Format only these fictional or non-sensitive notes for a attendance-window rail. Return strict JSON shaped as {"rows": [{"label": "string", "cells": ["string", "string"]}], "setting": "string"}. The columns are anonymous member code | available from HH:MM | available until HH:MM; the setting is Minimum simultaneous attendance count. Keep all supplied strings and quantities exactly; do not calculate, infer missing entries, invent dates or add advice. If any required value is missing, return an empty rows array and ask me for it separately. I will verify every cell against my source and manually transcribe rows using vertical bars before running the local calculator.

An AI response is not executed, fetched or trusted as a result. Missing values remain questions; the strict local parser checks the rows you actually enter.
