Many promoters run several, sometimes hundreds, of performances of the same production/show over the course of weeks or months.
FD automatically groups shows into event series based on event name, venue, cast and set list. This helps identify the impact of online marketing campaigns on sales and many other use cases.
Typically the limits set on the timeframe in which these shows are considered part of the series are 20 days before and after the selected event. If you come across an instance where this is not sufficient or does not meet your understanding, please contact us.
