Each range comes from a handful of completed windows.
How long you have
An Enchantments Core Zone Permit opening is usually gone inside 3 minutes
We timed every opening from the scan that first saw it to the scan that found it gone. On the permits we can time finely enough, most were taken well inside the hour.
3 min
Enchantments Core Zone Permit
90% gone within the hour · 58 openings
Dots are measured points: the start, the median, and the share still open at 60 minutes. The line between them is drawn straight, not modelled. Each median is published as an upper bound, so the real figure is that or faster. Only permits timed finely enough qualify: a figure needs measurement resolution under 15 minutes and at least 10 openings that stayed gone. The full rule.
The spread
The odds are not the same on every permit
Every permit we have scanned long enough, ranked by the chance we catch it opening in the next seven days. Each bar is a range, because the honest answer is a range.

The scale
Lowunder 31%Moderate31–60%Good60% and up71 permits, from 15–25% up to 75–85%. Each range is computed from a handful of completed seven-day windows and pulled toward a pooled average, so a short record cannot run away with itself. The permits with enough history are also the ones people set the most alerts on, so this set is not a random sample of the catalogue.
When to have an alert on
Half of all openings land within 35 days
For every opening we caught, we measured the gap between catching it and the night it was for. The busiest stretch is one to two weeks before the trip.
15–46
days out, middle half of openings
20,959
openings measured
82
days out, 95th percentile
This is the shape of the openings we have seen, rather than of every opening that exists: a date enters the sample when somebody has an alert on a window that covers it, so the curve carries our alert holders’ travel dates as well as the providers’ behaviour. Permits whose openings are mostly fetch noise are excluded.
What sits behind it
Openings we caught and confirmed
A forecast is only worth what the scanning behind it is worth. These are the openings our scanner caught and that stayed gone, on the permits whose openings we can measure cleanly.

Where these odds come from
Every figure here is measured from openings our own scanner caught, and recomputed once a day. Each one is the chance our scanner catches at least one opening on that permit inside the window shown. How we calculate this
Every permit we forecast
The whole list, by where it is
One link per permit that has a forecast, gathered under the park it sits in. It grows as more permits build up enough scan history to forecast.
The number beside each permit is its place in the same 7-day ranking the lookup above uses, out of 71.
