How to read court availability
The numbers in the grid
The number on a slot tells you how many courts you can start a booking from — for your chosen length, at that time. An empty cell means booked, or no data.
Why sometimes just “✓”
Some platforms only report that a court is free, not how many. For those we show a “✓” instead of a count. Count-based clubs tell us how many courts are free, but not which specific one — so a single court for the whole block isn't guaranteed.
Freshness
We re-check the near days every few minutes and the further-out days hourly. A slot that was free too long ago is dropped and marked unknown — we never show a stale slot as free.
