Paris runs three distinct event-density seasons. The first is the corporate season proper — September to mid-November, then February to early July — when most B2B briefs are scheduled. The second is the high-friction window: Fashion Weeks (January, March, June-July and September-October), Art Basel Paris (late October), Roland-Garros (late May to early June) and the Tour de France finish (final Sunday in July). The third is the low-pressure quiet window: late July, August, and early January.
Fashion Weeks (Haute Couture + Ready-to-Wear) drive a 30 to 60% premium on venue and supplier rates. Top hotels are entirely booked.
Art Basel Paris (late October) pushes the same premium across central Paris and the Grand Palais ecosystem.
Roland-Garros (late May to early June) ties up Champ-de-Mars, 16th arrondissement venues and creates transport friction.
Tour de France finish (final Sunday of July) shuts down the Champs-Élysées axis. Plan around or use it as a brand-led moment.
French public holidays (jours fériés) reduce supplier availability and add 50–100% staffing premiums. Many venues and suppliers close on 1 May, the one public holiday that is a day off by law for most employees.
Christmas corporate window (mid-November to mid-December) sees high venue pricing and limited weekday availability, with most dates locked six months ahead.
For maximum value and availability: mid-January to mid-February, late March to mid-May, mid-June to mid-July, and the second half of November. Each of these windows avoids the major pricing spikes and offers full supplier roster choice.
In 2027, France observes eleven public holidays: Friday 1 January, Easter Monday 29 March, Saturday 1 May, Saturday 8 May, Ascension Thursday 6 May, Whit Monday 17 May, Wednesday 14 July, Sunday 15 August, Monday 1 November, Thursday 11 November and Saturday 25 December. Two of them fall on a Thursday, Ascension and 11 November, and many French employees take the following Friday off to make a long weekend, a practice known as the pont. Suppliers are harder to staff on those Fridays and local attendance drops, so avoid scheduling a seminar or a product launch aimed at a French audience on 7 May or 12 November 2027.
Spring 2027 is also marked by two transport changes that affect joining instructions: the terminals at Charles de Gaulle are renamed on 16 March, and the CDG Express rail link between Gare de l'Est and the airport is due to open on 28 March. Our guide to airlines serving Paris covers the terminal changes.
Dates decide availability. Large congress venues book twelve to eighteen months ahead: see lead times and capacities in our guide to Paris convention and conference centres, and plan delegate arrivals with our guide to airlines serving Paris.
Four top-value windows: mid-January to mid-February, late March to mid-May, mid-June to mid-July, and the second half of November. Each avoids major pricing spikes (Fashion Weeks, Art Basel, December galas) and offers full supplier roster availability.
Fashion Weeks (January, early March, late June to early July, and late September), Art Basel Paris (late October), Roland-Garros (late May to early June), Tour de France finish (final Sunday of July), and the December Christmas corporate window all impose 30-60% premium on venue and supplier rates.
Generally avoid — many caterers and venues close 2-3 weeks. Mid-August is half-empty due to vacances d'été. Late August picks back up as suppliers reopen and corporate briefs resume.
