 #### Booking Update
 Execute the [update-booking.sh](concurrent-test/update-booking.sh) script to simulate concurrent
 updates for the same booking:
 
 ```bash
-$ concurrent-test/update-booking.sh 2022-09-16 2022-09-17 http:/localhost:80
+$ concurrent-test/update-booking.sh 2022-10-25 2022-10-26 http:/localhost:80
