How DAIZ Checks Opening Hours and Closures in Its Itineraries

DAIZ verifies opening days and long closures against your specific travel dates before a place is allowed onto your plan, so nothing in your itinerary should be shut when you arrive. If a place is closed on the day it was first slotted for, DAIZ either moves it to another day or leaves it out entirely. This applies to the day-by-day European itineraries DAIZ builds; it does not mean every venue on earth is covered, and it does not replace a final check on the venue's own site before you go.

What gets checked before a place reaches your day

DAIZ describes its engine as a layer "no chatbot has": real opening hours, closure dates, walking distances, and your own choices, checked against each other before a single place lands on your plan.

The checks fall into four groups:

• Opening days and long closures — verified against your travel dates.
• Walking distances — measured between consecutive stops.
• Your stated must-sees and tastes — placed first and used to shape picks.
• Crowd timing — used to decide which slot a place gets.

How a closure is handled: move, drop, or keep

The site gives concrete examples of the logic in action:

The pattern: a recurring weekly closure triggers a day swap; a multi-year closure triggers removal; a venue that is open when you need it stays. Your own priorities can override the default ordering — a must-see is placed first rather than being pushed around by convenience.

Why days don't bounce across the city

Each day anchors to one neighborhood, with real walking distances between stops, so you never cross the city twice. The site's own example: "Day 2 anchored in one neighborhood, no backtracking."

This matters for the hours check too. Because stops are clustered, a closure that forces a swap usually has a nearby substitute rather than sending you to the opposite side of the city.

What you actually receive

• The plan and the map in one view — every stop pinned, the walk between them measured, the whole day visible at a glance.
• Reasons attached to each day — which neighborhood it's anchored to, which timing was used, and which of your picks shaped it.
• One-tap changes — swap any place for a nearby alternative.

Limits worth knowing before you rely on it

• The verification covers opening days and long closures. It does not guarantee against same-day, unannounced closures (strikes, private events, weather).
• "Checked" is DAIZ's own claim about its engine; the site does not publish a list of which venues or cities are covered beyond the cities travelers plan with DAIZ.
• Pricing and account requirements are not stated on the pages reviewed here, so don't assume the planner is free or usable without signing in.
• Treat the itinerary as a strong first draft: confirm anything time-critical (timed-entry museums, restaurants you'd be devastated to miss) directly with the venue close to your trip.

When this approach fits you

Use DAIZ-style planning if you want a day-by-day European itinerary where the hard logistics — opening days, closure dates, walking distances — are resolved before you start booking, and where you can still swap stops yourself. If your trip depends on a single fixed reservation or you prefer to build each day from scratch, the value of the automated checks is lower.
