The couple

One Dutch and one from abroad, marrying on Saturday 26 June 2027. 140 guests, 35 of them flying in through Schiphol, 12 over seventy, 2 in wheelchairs. Within an hour of Amsterdam.

Twelve requirements

Each is one a planner cannot answer from a brochure, a visit or experience.

01

A 42° · B 36° · C 11°

The vows outdoors at sunset, facing open water, with nothing between the couple and the setting sun

The sun's bearing at that hour on that date, and whether a building, a tree line or a dyke is in the way, is geometry, not a brochure photograph

  • Sunset 22:05, 26 June
  • Bearing 312°
  • Line of sight in 3D
  • 3DBAG · AHN · solar position · A2

02

A 6% · B 4% · C 31%

No aircraft overhead during the twenty minutes of the vows

Which runway Schiphol uses depends on the wind; nobody tells a couple the odds of an overflight at that hour on a late-June Saturday

  • Evening wind
  • Runway use by wind
  • Noise contours
  • KNMI June wind · LVNL runway use · RIVM contours · B3

03

A 640 m · B 210 m · C 910 m

Music until 01:00 without a neighbour's complaint ending the party

Whether sound carries to the nearest homes depends on their distance, the prevailing wind and the municipality's rules for that spot

  • Nearest home
  • Wind in June
  • Event and noise rules
  • BAG · A1

04

A 0 permits · B 2 permits · C 1 permit

Nothing being built, demolished or dug within sight or hearing that summer

  • Permits within the radius
  • Plans in force and coming
  • Gazette · DSO · A2

05

A 0 closures · B 0 closures · C 1 closure

No road works, closures or other events on the access roads that weekend

They are decided months later by road authorities and municipalities

  • Road works and closures
  • Events that weekend
  • NDW · gazette · B2

06

A 38 km · B 41 km · C 33 km

The 35 guests from abroad at the venue within an hour of landing, and the elderly and wheelchair users without a long walk or steps

Travel time on a June Saturday and step-free access need data, not an estimate

  • From Schiphol
  • Straight line
  • BAG · straight line · A2

07

A 64 beds · B 118 beds · C 96 beds

Eighty beds within fifteen minutes' walk, so nobody drives after the party

The planner knows two hotels; the data knows all of them

  • Fifteen minutes on foot
  • Every lodging mapped, its beds from its own listing
  • OpenStreetMap · BAG · the lodgings' own listings · B2

08

A Clear · B Natura 2000 near · C Natura 2000 near

A drone shot over the water at golden hour

Whether the venue lies in a control zone or a nature area, and what is allowed over 140 guests, is airspace law

  • Within 500 m
  • Natura 2000 boundaries
  • Drone zones
  • Natura 2000 · A1

09

A 9% · B 9% · C 11%

Low odds of heat or a downpour, and shade if it is hot

The odds for one week of the year are statistics

  • That week's climate record
  • Nearest stations
  • KNMI climatology · B3

10

A 20.4 mag · B 19.6 mag · C 20.1 mag

A clear, dark sky for a late moment under the stars

Light pollution and the moon are not in a venue's description

  • Night light from satellite
  • Moon phase and rise
  • VIIRS night lights · B2

11

A 31 years · B 3 years · C 12 years

A venue whose company will still be there on the day, as the registers show it

A planner trusts the venue's reputation

  • Trade register
  • Insolvency register
  • Ownership of the property
  • KVK · insolvency register · gazette · A2

A 1924 · B 1911 · C 1998

A planner knows the venue's marketing story

What the watch caught

The brief is the intelligence, and it is right on the day it is written. The places do not stand still after that, so the watch keeps the brief right until the day: each card is a fact that arrived after the brief, with the odds without the watch and with it.
