Compare availability windows

Add multiple people, give each person one or more date and time ranges, and see the windows they all share.

This first release compares same-day date and time windows. Overnight ranges should be split across two dates.

People and availability

Add at least two people or sources. Each person can have one or more availability windows.

Scope for this MVP
  • Each availability window uses one date, one start time, and one end time.
  • Overlapping windows for the same person are merged automatically before comparison.
  • No calendar sync, timezone conversion, or invite workflow is included in this release.
