How often do "upcoming events" lists update?
"Featured" or "upcoming" events lists, often built into home pages and interior page sidebars, will update every day.
If your organization features many events on a single day, and your audience relies on up-to-the-minute updates there, you may want these lists to be accurate according to the current day's time. This can be accomplished with custom development. Contact Support with any questions you may have about events lists.
