Festival websites rarely start from a blank page each year. Pages built for one edition can stay live while the next one is being announced, and that's where expensive mistakes start. Before you pay for flights, a room or a rental van, check festival dates before booking against a source that names the exact edition you plan to attend. Here's how to do that, plus a few habits that save money and spare your group chat some arguments.
Why the year on the poster can mislead
An official site may still carry imagery from an earlier edition while new information rolls out. A poster in a hero banner doesn't confirm the date window for the edition you want. Sometimes the year in a page title, a ticket banner and a shared social card don't match. When they conflict, treat the dates as unsettled until an edition-specific page clears it up.
Find the edition-specific source
Start at the organizer's own destination. For those two events, that means Boom Festival's official site or Creamfields' official site, not a listing that copied details from somewhere else. Once you're on the official site, look for text that puts the year or edition right next to the dates. A date sitting near an old graphic doesn't count.
Third-party discovery cards, aggregator listings and reposted flyers are good for finding festivals. They're weak evidence for booking. Keep the two jobs separate: discovery tells you a festival exists, and the edition-specific source tells you when it happens.
Capture the source date
When you find the dates, take a screenshot and write down the day you checked. If plans change later, you'll know whether your information is a week old or a season old. Share the screenshot with your group so everyone is booking from the same page.
Directory listings work the same way. Each edition in the FestGeek festival directory shows a visible date-review timestamp, so you can see when its dates were last reviewed. That data comes from a reviewed catalog maintained by FestMob, which has the same owner as FestGeek. A recent review is a good reason to trust a listing more, but it doesn't guarantee the listing is error-free, so check it against the organizer before you pay.
Watch for separate weekends and tickets
Some events run over more than one weekend or sell different ticket types for different days. If a festival has separate weekends, confirm which one your ticket covers and book travel for that weekend only. Friends who buy at different times can end up on different weekends without noticing until it's too late.
Don't copy last year's schedule
It's tempting to assume this year will look like last year: same month, same days of the week. Dates can move from one edition to the next. Until the organizer publishes dates for the edition you want, last year's pattern is only a guess, and nonrefundable bookings shouldn't rest on a guess.
A quick pre-booking checklist
-
Open the organizer's official site, not a reposted flyer.
-
Find text that names the edition or year next to the dates.
-
If the poster year, page title and ticket banner disagree, wait for clarity.
-
Screenshot the dates and note the day you checked.
-
Confirm which weekend or days your ticket covers.
-
Compare against a directory listing's review timestamp, then book.
