Annual budgets assume each trade show happens once a year in the same month. Many do not. Some run every other year, some change month or venue between editions, and many brands now run separate shows in several countries. If you plan more than one edition ahead, the show’s cycle matters as much as its next dates. The examples below were checked on organisers’ sites on 19 October 2026.
Annual and biennial shows
SIAL Paris describes itself as a biennial event; its 2026 edition ran in October, and the next is not expected the following year. A biennial show changes the planning arithmetic. Missing an edition means a two-year gap, and figures from the previous edition are two years old by the time the next one opens.
When a show runs every other year, check whether the organiser runs a related event in the years between, and whether that event reaches the same buyers.
Shows that change month
A show held in the same city every year can still move. Gulfood‘s 2026 edition was in January; the official site gives 15 to 19 March 2027 for the next. IMEX America says it “comes early in 2027”, with its trade show on 28 to 30 September. If your planning calendar rolls last year’s dates forward automatically, these are the shows it will get wrong.
Shows that change venue or layout
Venue changes are just as disruptive. Gulfood now runs across two venues, Dubai World Trade Centre and Dubai Exhibition Centre. Within a single venue, layouts change too: Messe Düsseldorf says MEDICA 2026 introduces a new hall and topic structure, and Ambiente is reorganising its product areas for 2027. Last year’s hall notes can send you to the wrong place.
One brand, several editions
Many brands now have editions in different countries, each a separate event with its own dates, audience and contract:
- RX’s WTM portfolio runs World Travel Market London, Arabian Travel Market, WTM Africa and WTM Latin America.
- Bett runs in the UK, Brazil, Asia and, from 2027, the United States.
- Messe Berlin’s ITB Berlin and ITB Asia share a name but not registration.
- Messe Frankfurt runs Automechanika in Frankfurt and, separately, Automechanika Birmingham.
- Koelnmesse’s Anuga in Cologne has a partner event, Anuga Select South Africa, run with dmg events.
Check you are reading the right edition’s site before you register, and do not assume that acceptance onto a hosted buyer programme for one edition carries over to another.
New, renamed and relaunched events
Portfolios change. Koelnmesse has acquired Imaging World, which it says will hold its first edition at the new location in September 2027 under the name Imaging World inspired by photokina. Messe Frankfurt is launching Intersec Europe in Frankfurt in September 2027. Anuga Select South Africa is presented on the website previously used for Africa’s Big 7. Older listings under a previous name can carry outdated dates, venues or organisers.
A first edition has no track record, so treat its audience forecasts with particular care. See understanding attendance and exhibitor figures.
Shows that publish dates years ahead
Some organisers publish future editions early. AIME lists 14 to 16 February 2028 alongside its 2027 dates, and the SEMA Show lists 2 to 5 November 2027. Early dates help long-range planning, but they are still subject to change. Treat them as provisional until the organiser opens registration for that edition.
A planning checklist
- Record the show’s cycle (annual, biennial or irregular) and where the organiser states it.
- Record the month, city and venue for the last two editions and the next one, with sources.
- Note any brand editions in other countries so the team does not register for the wrong one.
- Flag first editions, renamed events and layout changes for extra checking.
- Set a date to re-check each show before money is committed, and earlier for shows that have moved recently.
For checking a specific edition before you book, see checking official show dates before booking travel. Browse upcoming editions in the trade show calendar.
