Some ideas on this :
1) You could probably try using the TYPE 42 field to create a date $value of today. Dummy/Alias that field onto the same storage field (using standard + free) And then add that field to the search/list type. The event that matches will be displayed.
2) If you have two fields of the event datestart and dateend (or use some addition/subtraction), then you might be able to achieve the same (and/or with method above)
Maybe this will help with some ideas too :
