Every venue, every programme — the flag ceremony, the air show over the Danube, the Holy Right procession, and the night of light and fire on the river.
If you see nothing else on Thursday the 20th, see these.
The raising of the national flag and the commissioning of new officers — the formal opening of the day.
Military aircraft over the Danube between the Chain Bridge and Margaret Bridge, with live commentary from both banks.
A 30-minute drone, light and projection performance telling Hungarian history, closing with ten minutes of fireworks. Repeated at 22:00.
Every programme below is free. Times are as published by the organisers.
Ceremony by day, open-air party by night. The Parliament building itself opens to visitors free of charge, with no booking.
The river itself is the stage. The evening show is concentrated on the 1.5 km of Danube between Margaret Bridge and the Chain Bridge — organisers say the Buda side gives the clearest view.
The gentlest venue of the festival — a car-free island of concerts, children's workshops and an illuminated garden in the rose beds.
The Festival of Folk Arts fills the castle district with traditional craftspeople for five days — the longest-running programme of the week.
The largest gastronomic festival in the Carpathian Basin: handcrafted delicacies, the official Saint Stephen's Day bread, and this year's Cake of Hungary — including a sugar-free version.
Two nights of international electronic music on a flat riverside quay, with a light show over the water.
A shaded community rest area and gastro garden in the middle of the city, with screens — the place to retreat to when the embankments get crowded.
One of Hungary's most significant religious events: the Holy Right — the preserved right hand of King Saint Stephen — is carried through the streets of the inner city, followed by mass at the basilica.
Military technology up close: laser target shooting, VR simulators, a drone obstacle course and explosive-detection dog demonstrations. Vajdahunyad Castle is also free on these days.
