As marketers, we often plan in quarters but shoppers don’t live by calendars. They live by moments. Summer is packed with them: music festivals that light up social feeds, global sports events that bring people together, and citywide celebrations that shift moods and trends overnight. And the smartest brands are syncing with culture. 

This summer, tap into the events your audience already cares about and turn them into meaningful, well-timed marketing opportunities. 

Here's your guide to what's happening across the UK and the continental Europe! 

Use this calendar wisely for:

  • Editorial planning: Weave a campaign calendar that follows these events
  • Geo-segmented promotions: Localize campaigns (e.g. Glasgow shoppers get TRNSMT offers, Scottish audiences get Loch Lomond offers).
  • Shop-the-festival-look experiences: Inspire your app users and web visitors with shoppable videos.
  • Event-based bundles for higher AOV: Combine relevant items for each festival, convert, or match. Introduce these bundles to relevant segments on your app and website.
  • Interactive games: All the festivals, sports organizations, and bands come with a rich history and playful traditions. Create trivia games to bring this hype to your own digital stores or social media channels.
  • Cross-channel synergy: Use real-time content—Stories, live tweets, match trackers—feeding ads back to product pages with event-related creative.
