Ask HN: Do you know a calendar which shows how many days until event starts?

Is there any desktop calendar tool which can do that? Currently I use Google calendar but it doesn't provide this kind of information. It would be super awesome for me to have a Top 10 countdown list like: • 3 days until Concert A • 42 days until Concert B • 188 days until doomsday • … I would also prefer a non-cloud, non-registration offline calendar.
