# Study-room bookings

Synthetic study-room reservations from a fictional campus library. See `README.md` for the columns.

## Reporting rules

- **Fiscal years, not calendar years.** A fiscal year runs July 1 to June 30 and is named for the year it ends, so FY2026 is July 1, 2025 to June 30, 2026. Use fiscal years in every chart, table and summary.
- **Each `booking_id` counts once.** The export repeats some rows, so de-duplicate on `booking_id` before counting anything.
