About the data

The calendar

We collect published dates from event organizers, universities and official calendars. Coverage runs from Oct 1, 2026 – Dec 31, 2027. It is a selection of major events, not a complete city listing or a live feed. Provisional dates are marked.

Matching your stay

We count hotel nights, excluding the check-out date. Nearby events use a planning allowance of one to three days before an event and up to one day after. These are estimated travel days, shown separately from the official dates.

Comparing dates and prices

The week comparison keeps your stay length and moves it seven days either way. We do not collect hotel prices, so fewer events does not guarantee a lower rate. An event match also does not prove the cause of a price increase.

Booking.com links use your chosen dates, two adults and one room. Google Hotels links include the city and dates in a search. Confirm the details on the booking site. These are ordinary links; we do not earn a commission.

Updates and corrections

Dates can change after our review. Every event links to its source below. Send a correction with the event name, city and official announcement. Feedback is public; leave out personal booking details.
