Tomorrowland 2026: the clash guide

Set times for Tomorrowland 2026 are out — over 400 sets per weekend across 16 stages, on 17–19 July (Weekend 1) and 24–26 July (Weekend 2) in Boom, Belgium. Which means the annual heartbreak has begun: some of the artists you came for are playing at the same time.

This guide covers the biggest clashes of both weekends, based on the published timetable, and a saner way to solve them than arguing in the group chat.

How to think about a clash

Three rules from festival veterans:

Weekend 1 (17–19 July): the big five clashes

Friday: Martin Garrix vs Hardwell b2b Sub Zero Project. The Mainstage closer (23:50) overlaps the Great Library b2b (00:00) by nearly an hour. Big-room anthems or the harder edge — this one splits friend groups down the middle.

Saturday, the brutal hour — 22:00 to midnight. Saturday evening is the single most clash-cursed stretch of Weekend 1. Armin van Buuren's Freedom By Bud set (22:00) collides with three different Mainstage/side-stage giants: Dimitri Vegas & Like Mike (22:20, 75 minutes of overlap), David Guetta (23:35), and Steve Aoki on Planaxis (23:00). Lost Frequencies (21:30, Great Library) loses 45 minutes to Armin too. You cannot see them all. Choose two, split one.

Sunday: Calvin Harris vs Amelie Lens. The festival's closing night sums up the whole Tomorrowland dilemma in one clash: Calvin Harris on Mainstage (22:50) against Amelie Lens on Atmosphere (22:30), a full hour of overlap. Pop-dance singalong or Belgian techno homecoming. If your library leans even slightly techno, Atmosphere will be the better hour — and I Hate Models (22:00, Freedom By Bud) makes the case even stronger.

Weekend 2 (24–26 July): where it hurts

Friday: Hardwell vs Alesso. Mainstage closer (23:50) against Freedom By Bud (23:00) — 40 minutes of overlap to open the weekend.

Saturday is the hardest night of the summer. Calvin Harris closes the Mainstage at 23:45 and clashes with John Summit (Crystal Garden, 22:30), I Hate Models (Atmosphere, 23:30 — a full hour of overlap) and Timmy Trumpet (Freedom By Bud, 23:00). Earlier that evening, Dimitri Vegas & Like Mike (22:30) eat 75 minutes of John Summit's set, and Armin van Buuren (21:25) collides with Lost Frequencies (21:30). House heads: Summit. Techno heads: I Hate Models. Everyone else: flip a coin and split the difference.

Sunday: Martin Garrix vs Amelie Lens presents Aura. The Weekend 2 finale — Garrix on Mainstage (22:50) against Amelie Lens's Aura showcase (22:00, Freedom By Bud), with Steve Aoki (21:45) clipping the start of it too.

Solving clashes for your taste — automatically

Everything above assumes the big names are the ones you care about. They might not be. Across 400+ sets, the real question isn't "Guetta or Armin?" — it's which 30 of these 400 sets are worth your weekend, and only your own listening history can answer that.

That's what FestWave does: export your Spotify liked songs (two minutes, no login), upload the file, and every set in the Tomorrowland timetable is colour-coded — green for artists already in your library, amber for acts that match your sound. Clashes resolve themselves when you can see that one side of the clash is a 95-point match and the other is just a famous name. Your library is read entirely in your browser and never uploaded.

FAQ

How does FestWave know my music taste?

You export your own Spotify Liked Songs with the free Exportify tool and upload the CSV — or just pick your favourite artists by hand. The file is read in your browser; your music data never reaches our servers.

What does FestWave cost?

Nothing right now — every 2026 festival is completely free, including the full personalised, editable grid. Just pick a festival and add your taste. Festivals in later years may become paid.

Why is there no “Log in with Spotify”?

Spotify's API programme is closed to new independent apps, so FestWave doesn't connect to your account at all. Exporting the file yourself is your right as a user — and it means we never see or store your listening data.

What do the colours in the grid mean?

Green (★ Liked) — the artist is in your library. Amber (◆ Taste) — the act fits the genres you listen to most. Everything else just plays. You can click any set to re-tier it yourself.

Are the set times official?

Set times are curated from public sources and verified by hand, but they are provisional — festivals shuffle schedules late. Always confirm in the festival's official app. FestWave is an independent tool, not affiliated with any festival, artist, or Spotify.

Do I need an account?

No — FestWave works completely without one, and that way we store nothing about you (your taste and saved festivals live in your browser). But a free account — just your email, no password — keeps them in the cloud, restores them on any device, and can email you about lineup changes or new festivals matching your taste.

What if I clear my browser or lose my device?

With an account, just sign in anywhere and press “Sync” — your taste and saved festivals come back. Without one, they live only in this browser. Questions? Contact support@festwave.app.
