[EventCalendar] Showing the event post ONLY on the day it occurs

[Alessandro]

How do you make EventCalendar display the post corresponding to an
event ONLY on the day it occurs, but otherwise hide it from view on
the front page?

For example, an event/post for Christmas should not appear anywhere on
the site until it's December 25. On that day, it should appear on the
blog's front page, with its "Merry Christmas" message. On December 26,
it should disappear again.

Any ideas?

Thanks for the help!
