Conventions

• Times are naive local wall-clock (America/New_York, America/Chicago) unless the column ends in _utc.
• Hour grids skip the nonexistent spring-forward hour; the fall-back 01:00 hour holds two real hours (dst_merged_hour in *_city_hour).
• Tables are indexed by when things happened. Lag every feature by >= 1 hour before predicting hour t (CTA: previous day; drive times: previous year).
• 0 means an observed zero; a missing row or NULL means no data. MTA ridership starts 2020-07; zones without a station are absent from mta_zone_hour / cta_area_day (see the station counts in the zones tables). Alert and flight tables only have rows for hours with activity.
• Zone-hour median_* columns describe that hour's pickups and are NULL when it had none. Dropoffs are counted where and when trips ended. Like pickups, all of them are only known once the hour is over, so lag them >= 1 hour.
• Events: schedules are known in advance, so they may describe the target hour. ESPN gives start times; end times are estimates (typical length per league). setlist.fm gives dates only, so concerts are placed at 19:30-23:00. ESPN attendance is reported after the game. Canceled and postponed games are dropped. Out-of-zone venues have zone NULL; some list entry_zones where their crowds enter the city (e.g. MetLife -> Penn Station, Port Authority).
• Splits are by time only: train 2019-2022 excluding 2020-03..2021-06, early-stop 2023, calibrate 2024, test 2025+.
