December 24, 2026 is a Thursday, and December 25 is a Friday. France.fr’s Christmas Eve article, updated November 20, 2020, describes the custom, not a 2026 menu. The réveillon is the long dinner on the 24th, sometimes in a restaurant. The article’s typical plate is oysters, salmon, or foie gras, then turkey with chestnuts, capon, or duck, then cheese and a bûche de Noël. The meal used to follow Midnight Mass. Many families now eat first, or go to an earlier vigil. Gifts were traditionally opened on the morning of the 25th, and opening them on the 24th is now common too. Outside Alsace and Lorraine, December 25 is the only official Christmas public holiday.
There is no 2026 figure here for how full restaurants get. If the dinner is the point of the trip, arrange it before you fly. Museum hours are in what is open over Christmas and Paris in December.
Notre-Dame has not published Christmas 2026. Not yet announced; in 2025 the cathedral’s page listed Eve Masses at 4pm, 6pm, and 8pm, a vigil at 11pm with the Maîtrise, and Midnight Mass at midnight. Christmas Day was Mass at 8:30am, Gregorian Mass at 10am, Mass at 11:30am, vespers at 5:15pm, and a diocesan Mass at 6pm. No booking was required. Arrive 30 minutes early and use the Mass door in the center of the parvis, opposite the Last Judgement portal. Do not copy those hours onto 2026. An undated Notre-Dame page still says “Tuesday, December 24,” which is not this calendar, so it is unused.
The gourmet walk is the food version of the same week: three hours on the Left Bank, eight people at most, minimum age 6, seasonal tastings, a market stop, and a hot drink. It is a 4.44 from 18 reviews.
