Multi-Person Availability Merger
Union participant intervals, validate identities and datetime forms, and add meeting-length filters, buffers and a UTC-aware timeline.
The problem it solves
Multi-Person Availability Merger [](https://github.com/loganpendragonmultiverse/multi-person-availability-merger/actions/workflows/ci.yml)
Who Multi-Person Availability Merger is for
- People who need a small, purpose-built utility instead of a broad platform.
- Users working with availability, scheduling, overlap who want the documented v1.1.0 behavior.
- People who prefer an open-source release with visible limitations, source, and license terms.
Intended result
Union participant intervals, validate identities and datetime forms, and add meeting-length filters, buffers and a UTC-aware timeline.
This summary is reconciled from the current catalog and repository documentation.
Features in v1.1.0
Capabilities below come from the current project README and release documentation.
[](https://github.com/loganpendragonmultiverse/multi-person-availability-merger/actions/workflows/ci.yml)
Merge pasted availability lists and return overlapping windows without calendar access. The command uses explicit UTF-8 JSON input and produces reviewable JSON or Markdown output.
Verified examples
Screenshots are shown only when the current README references a local source image. Otherwise, repository example files are linked directly.
Platforms and implementation
The public release claims only the cataloged platforms and technologies.
Supported platforms

What changed in v1.1.0
Union participant intervals, validate identities and datetime forms, and add meeting-length filters, buffers and a UTC-aware timeline.
availability-merge examples/sample.json --format markdownEach person may provide a unique string id; otherwise their unique name is the ID. Use minimum_minutes and buffer_minutes as nonnegative integers. Buffers trim each person's unioned availability before calculating overlaps; meeting length applies to each continuous slot with the same participant set. timezone_mode is auto, utc (explicit offsets required), or naive (wall times only). Offset-aware inputs are converted to UTC before duration arithmetic. Mixed aware/naive times and duplicate IDs are rejected. Named-zone guessing and calendar writes are not performed. Markdown includes a start/end/minutes/participants timeline.
Quick start
The shortest documented path into the current release.
python -m pip install .
availability-merge examples/sample.json
availability-merge examples/sample.json --format json --output report.jsonThe example documents the v1 input shape. Existing report files are never overwritten. Source inputs are read-only except where the documented purpose explicitly creates a new output artifact.
Current limitations
These boundaries are part of the product and prevent the page from implying unverified capability.
Intervals use explicit ISO datetimes. The tool does not resolve time zones, recurring events, travel time, or calendar conflicts not supplied.
Privacy and licensing
Review the actual data boundary before using a tool with sensitive inputs.
Privacy and safety
The tool runs locally and does not upload input or include telemetry. Python 3.10 or newer is supported on Windows, macOS, and Linux.
License and release
Multi-Person Availability Merger is published under MIT. The current cataloged release is v1.1.0, published 2026-09-07.
