About Theme Park Calendar

What the calendar contains

The calendar collects seasonal events, new rides, shows, maintenance periods, fan events and openings. Every listing belongs to a park or to an event organised by a park, such as the Efteling and Anton Pieck collectors fair in Breda.

You can follow parks, filter by category, set a reminder and use a private calendar feed. No account is needed to browse.

Where the data comes from

We do not copy events from lists without a source. A scheduled worker reads official park pages, maintenance pages and Dutch park news. For each article it determines which events and dates are present.

1. The worker fetches a source.
2. The text is read and split into individual events.
3. Dates, categories and locations are checked.
4. Duplicates are merged and every listing gets a source link.
5. When confidence is low, an event goes to the review list in the admin area.

Processing is automatic. An editor can remove an event or publish a review item afterwards.

Maintenance

For parks with a public maintenance calendar we add closed rides and maintenance periods as separate events. This includes Efteling, Walibi Holland, Drievliet, Madurodam, GaiaZOO and Avonturenpark Hellendoorn. Parks that only publish daily opening hours do not get invented maintenance data.

Corrections

Parks can change dates. Always check the park website before you travel. If you find an error, email hello@themeparkcalendar.com with the source.
