Although the events in the film supposedly take place during a swelteringly hot summer in Limburg (on the day the statue of Maria cried for the first time it was over 34 degrees Celsius, and fans are whirring throughout the movie), the date of the CT-scan is stated to be 17 October 2021 according to the machine. It would be miraculous if temperatures rise above 30 degrees in October in The Netherlands. Probably 17 October 2021 was the production date.
