9am PT = What Time in Beijing? Is a Question Your Calendar Should Answer

Description and use

A Python CLI that locally converts times and finds shared windows for teams across time zones, eliminating manual calculation errors.

Remote teams struggle with time‑zone conversions, leading to scheduling errors and wasted time.

The CLI eliminates manual conversion errors, provides accurate scheduling windows, and keeps all data local.

1. Install the CLI (Python 3, optional tzdata on Windows).
2. Run python timezone_planner.py convert "9:00 AM" America/Los_Angeles Asia/Shanghai Europe/London to see what 9 AM PT means for each zone over the next 7 days.
3. Run python timezone_planner.py overlap "Alice:America/New_York:09:00-17:00" "Bob:Asia/Tokyo:10:00-18:00" "Carol:Europe/Berlin:09:00-17:00" to find shared 15‑minute windows, skipping weekends.
4. Use --json for machine‑readable output or integrate exit codes (0=overlap, 1=no overlap, 2=bad args) into cron jobs for notifications.

A single-file Python CLI (pure standard library — the only optional extra is tzdata on Windows) that answers the question locally
