Check course detailsA practical booking habit
Count from the day you want to play.
If a course has a seven-day window and you want Saturday, start checking the previous Saturday. The precise release time may still depend on the booking system.
Always use the official booking route for the live calendar. Birdii compares published rules but does not scrape or reproduce live availability.
