Calendar Southampton · 2026-27

Built from port schedules, fixture lists, term dates and licensing notices. Rebuilt nightly.

The working version of all this

Hear it before
it happens

The calendar watches the port schedule, the fixture list, the term dates, the roadworks register and the forecast, every night. When something that matters to your zone changes or approaches, you get one short email that tells you what to do about it.

What lands in your inbox

Monday, 7am

The week ahead in one strip: tier per day, the drivers behind them, one action if the week needs one. Readable before the first delivery arrives.

Three weeks out

A planning alert for every critical day, sent while the rota and the stock order can still change.

72 hours out

The tactical version, merged with the live forecast: terrace verdict, final staffing nudge, parking note for booked guests. Plus a weather alert whenever the forecast crosses a terrace threshold, in either direction.

A real one, verbatim

Operational alert: CRITICAL, Sat 12 Sep, Oxford Street
What lands Five-ship turnaround, Saints at home to Bristol City at 3pm, 6,000 students moving into halls, Music in the City across fifty venues.
Expect Lunch covers up 30 to 40 percent. Walk-ups sustained all afternoon. Elevated no-show risk on evening bookings, with city parking saturated 10am to 3pm.
Do now Overbook lunch by 15 percent. Deposits on evening tables of four plus. Send booked guests the parking and trains note by 10am.
Confidence Confirmed. Kickoff could still move for television; you would hear the same day.

Where the numbers come from

Port movement schedules and terminal allocations. The published fixture list, with television moves tracked. Both universities' term and graduation calendars. Council roadworks and licensing registers. National Rail engineering notices. Met Office climate records and the live forecast. National benchmarks from ONS, CGA RSM and UKHospitality. Every date in the system carries a confidence flag: confirmed, likely or projected, and the projected ones are drawn hatched until they firm up.
